Genetics. Q.

kenwood · 09-17-2006, 02:34 AM

Genetics...Their from your mom&dad right? soo do i have my dad genetics?

Dad:
Height: 5'6"
Weight: 150lbs
BF%: 8-10%

Mom:
Height: hmmm prolly round 5'7-8"
Weight: prolly around 110-115lbs
BF%: shit i dunno low iguess (skinny)

could i have my dads genetics or moms or what? me:

Height: 5'5-6"
Weight:183lbs
bf%: 16-18%

is it possible i have my dads genetics? i mean is it possible i could have on of my ancestors genetics? my g-pa is 6' and my g-ma is 5'3". i have 6uncles, a few of them are pretty muscular and are 6'-6'3"tall and some of them are 5'6-9". so a few of them surpassed their parents height. could I? i'm almost or as tall as my dad but i'm bigger and way stronger than him but he's ripped as hell(6 pack and shit) haha. could i destroy my parents genetics?

Genetic make-up is massively determined by heriditory (sp?) from parents/family tree.

But also, there is largely an individual factor, genetics determined by yoursef. I'm very hairy but my mum and dad are not. My dad has lean legs, whereas I struggle stripping the fat of my legs.

There are many factors to consider but personally I believe you have inherited the genetics from your mum because you tend to be a moany arse and changing your mind every minute just like a woman. However, your Intellectual is more of a Individual factor, your mum graduated from school and you....you let mama down.

ERM, what are you GOD? LOL Sorry but there is no individual factor, there are environmental factors.

You could say you are what you eat, that is about it.

Ok where do you lads think you can 'magic' characteristic out of nowhere?

All living creatures are the product of nature (genes) and nuture (environment), and the two have an impact on each other, they dance together.

Genes are not written in stone, depending on the temperature and food availability, some species will express one sex or the other.

There are examples for humans too, few but there are some.

They think they have located one of the genes for aggression, and screened a number of young men in care and a control group for this gene.

THey followed as many as they could to determine the effect of the gene.

They found out that the young men required the gene for aggression AND a undesireable upbringing to become involved in crime and violence, so you need the GENE for aggression and the ENVIRONMENT to express a violent or antisocial tendency.

I have the paper listed somewhere if anyone is interested.

Okay yea, 'ENVIRONMENTAL FACTOR'S' such as exercise and diet (being THE 2 big one's.)

E.g. , MY DAD - does tons of cardio a day/light cardio and has two shitty meals a day. Has ripped legs (amazin built calves too)

Me - HIIT cardio 1-2 a week, weights 3x's a week, lots of quality rest, 6-7 quality meals a day. Have fat bulky legs (calves are terrible.)

An why am I so hairy, IS THAT AN ENVIRONMENTAL FACTOR?

NO, Its BULLSHIT, no such thing as Individual factors, yea rite...

TJ Cline · 09-17-2006, 03:44 AM

My guess is both are aggressive folks with less than a GED.....so you better break the cycle soon son.

On a side note you are not allowed to be in the Canine Club for obvious reasons.

Your genes descend from your ancestors. You have genes from your grandparents, their parents and so on. If one person in your family was hairy, then you have a chance of being hairy too.

I'm also very hairy. My dad is not hairy. And my grandpa on my moms side had about 3 hairs on his chin, although he had a full head of colored hair well into his seventies. My dad said that his dad, who died before I was born, was really hairy. I'm really into genetics and biotechnology and although we've learned a lot recently there's still a lot of things we don't know about how genes express themselves and what signals turn them on. There's prolly key genes that need to be activated during adolescence and if they're not activated then you're not gonna be hairy. This applies to a lot more than just body hair though. Someone please correct me if I'm wrong on anything here.

Triple Threat · 09-17-2006, 09:18 AM

Don't they teach stuff like this in school?

Witchblade · 09-17-2006, 09:22 AM

Look, discussing this matter here is just silly for a huge number of reasons.

- Humanity doesn't know everything about genetics yet.

- You can't change your genetics.

- This is a friggin' bodybuilding training forum.

- The matter requires a lot of basic understanding about genetics you obviously don't have, no offense (not to mention your question screams 'I dropped out of school' which doesn't seem like a good thing on this board. Again, no offense.).

- The matter is unthinkably complicated. You could get a rough guess of what you're actually asking and how complicated it is by asking yourself: 'Why is that millions of professional scientists have brainstormed over this for centuries without even getting close to working everything out?'

So in short: The only question I can answer here is 'do I have my parents' genetics?' The answer: 'Yes, your genetics are a mixture of your parents' genetics.' Not that this will do you any good whatsoever.

**CowPimp** · 09-17-2006, 09:44 AM

There are also things called recessive genes. As well, you have to consider the environment you grow up in heavily, as certain genes are better activated when placed in a certain type of environment.

Take my height for example. My dad is about 5'5" and my mom is about 5'4". I'm 6 feet tall, maybe a tad more. Where the fuck did that come from? None of my aunts and uncles are as tall, and my grandma and grandpa on both sides were/are pretty short too. I'll tell you where it came from: big eating. I was always fairly active in my younger days and my body doesn't like to go hungry. Without the proper nutritional environment, the others in my family probably just didn't reach their full potential with regard to height.

Maternal dietary influences during gestation appear to influence the rate of bone growth during adolescence, as does physical activity and diet.

That might explain CowPimps unusual height in his family. His parents and grandparents may have had deficiencies in dietary vitamin E, coupled with a lifestyle that may be significantly different that the one he enjoyed as an adolescent.

-------------------------------------------------------------------

Developmental Origins of Osteoporotic Fracture: the Role of Maternal Vitamin D Insufficiency. Cyrus Cooper5, Kassim Javaid, Sarah Westlake, Nicholas Harvey and Elaine Dennison. J. Nutr. 135:2728S-2734S, November 2005

Osteoporosis is a major cause of morbidity and mortality through its association with age-related fractures. Although most efforts in fracture prevention have been directed at retarding the rate of age-related bone loss and reducing the frequency and the severity of trauma among elderly people, evidence is growing that peak bone mass is an important contributor to bone strength during later life.

The normal patterns of skeletal growth have been well characterized in cross-sectional and longitudinal studies. It has been confirmed that boys have higher bone-mineral content, but not volumetric bone density, than girls. Furthermore, there is a disassociation between the peak velocities for height gain and bone mineral accrual in both genders.

Puberty is the period during which volumetric density appears to increase in both axial and appendicular sites. Many factors influence the accumulation of bone mineral during childhood and adolescence, including heredity, gender, diet, physical activity, endocrine status, and sporadic risk factors (e.g., cigarette smoking).

In addition to these modifiable factors during childhood, evidence has also accrued that fracture risk might be programmed during intrauterine life. Epidemiological studies have demonstrated a relationship between birthweight, weight in infancy, and adult bone mass. This appears to be mediated through modulation of the set-point for basal activity of endocrine systems such as the GH/IGF-1 and parathyroid hormone/vitamin D axes. Maternal vitamin D insufficiency is associated with reduced bone mineral acquisition during intrauterine and early postnatal life.

Furthermore, both low birth size and poor childhood growth are directly linked to the later risk of hip fracture. The optimization of maternal nutrition and intrauterine growth should also be included within preventive strategies against osteoporotic fracture, albeit for future generations.

FUCK genetics just eat sleep & train & then just open ur mouth & eat somemore....FUCK GENETIC GUYS! i have shit genetics but i care a damn...i just train hard eat a lot very clean 6-7 meals & sleep a lot too....SHIT! my parents are sick of my eating habits. LOL

Tatyana · 09-17-2006, 02:07 PM

We are not really discussing genetics, we are discussing heretibility.

Heretibility is a measure of what is varying, not what is determining.

'In a true mediocracy, where all have equal opportunity and equal training, the best athletes will be the ones with the best genes. Heretibility of athletic ability will approach 100%.

In the opposite type of society, where only the priveledged few get sufficient food and the chance to train, background and opportunity will determine who wins. Heretibility will be zero.

Paradoxically, therefore, the more equal we make society, the higher heretibility will be, and the more genes will matter'. From Nature Via Nuture by Matt Ridley

...'and the more genes will matter'. and in 'equal' societies, such as the Western World, some will just think it so unfair that they can't play pro ball or be a bodybuilder, and someone with a bodybuilder physique could not have obtained it naturally.

I remember vaguely something in a Scientific American (maybe we have loads of journals lining the corridors on the way to the tea room) about the expression of genes. They think it has more to do with what is stuck on the outside of the packaged DNA or chromosomes, like sulphurs and sugars etc.

SO any sort of nutritional variation, like a famine, is thought to change the expression of genes for up to two generations.

Sorry, I can't be bothered to google for anything proper on this subject of DNA expression

Tatyana, you are referring to histones, proteins that sit on top of DNA helices and act as "housekeeping" systems that both protect DNA and are one of several control mechanisms that regulate expression.

Histones are aceylated/deacetylated by methyl transfer. The methyl donors are most commonly sulfur containing amino acids (methionine and cysteine) vua methyltransferase enzymes. This is a normal DNA expression control mechanism, most notable as parental imprinting of gametes - this reflects the influence of environmental factors on offspring expression within a limited number of genes. It also occurs frequently during the lifetime of an organism, a fail-safe backup system for the regulation of oncogenes, bits of DNA leftover during evolution of a species within "shit-filler genetic material present between genes within chromosomes. Its conserved within the genome to provide for emergency sequences that may afford "an out" if environmental conditions change. Histones are also modfied by other reactions such as glycosylation (addition of sugar groups to the aminoacid backbone of histone complexes) under abnormal cell conditions. Example: hyperglycemia.

Histone methylation is an example of the plasticity of gene expression.

All science aside.... you cannot change your genetics.

You CAN change your attitude, eating habits, training and overall bodybuilding knowledge.

Do not worry about what cannot be changed. Strive to be the best and let God handle the rest.

Yes there are histones and something NEW! Histones also help with the DNA packing, 4 globular ones and one longer protein, H1-H4 if I remember correctly!

OOOOOOOOOOOO this is great, you guys are all science geeky!

WELL, that you cannot change your genetics may not be true. You can change the expression of genes, for example, increasing the amount of growth hormone that is released by the way you train and dieting.

GH pathway, hmmmmmmm, IGF-1 (plus more cytokines I am sure), anyway, in a nutshell, it will increase protein synthesis in muscle tissue.

Our environment (diet, exercise, stress, amount of sunlight....) has an impact on our DNA, and the expression of DNA.

Nope. Totally true. You cannot change your genetics.

>You can change the expression of genes, for example, increasing the amount of growth hormone that is released by the way you train and dieting.

Dieting, yes. Training, to a lesser extent. You forgot photoperiod and sleep, perhaps the most significant factors influencing growth hormone release.

>Our environment (diet, exercise, stress, amount of sunlight....) has an impact on our DNA, and the expression of DNA.

The primary effect of diet and lifestyle is on the variable expression of DNA. Not sure what you mean by "the impact on our DNA". Vague wording.

I see you decided to use Google after all.

Histones are aceylated/deacetylated by methyl transfer. The methyl donors are most commonly sulfur containing amino acids (methionine and cysteine) vua methyltransferase enzymes. This is a normal DNA expression control mechanism, most notable as parental imprinting of gametes - this reflects the influence of environmental factors on offspring expression within a limited number of genes. It also occurs frequently during the lifetime of an organism, a fail-safe backup system for the regulation of oncogenes, bits of DNA leftover during evolution of a species within "shit-filler genetic material present between genes within chromosomes. Its conserved within the genome to provide for emergency sequences that may afford "an out" if environmental conditions change. Histones are also modfied by other reactions such as glycosylation (addition of sugar groups to the aminoacid backbone of histone complexes) under abnormal cell conditions. Example: hyperglycemia. Histone methylation is an example of the plasticity of gene expression.

You CAN change your attitude, eating habits, training and overall bodybuilding knowledge. Do not worry about what cannot be changed. Strive to be the best and let God handle the rest.

You cannot change your genetics. >You can change the expression of genes, for example, increasing the amount of growth hormone that is released by the way you train and dieting. Dieting, yes. Training, to a lesser extent. You forgot photoperiod and sleep, perhaps the most significant factors influencing growth hormone release. >Our environment (diet, exercise, stress, amount of sunlight....) has an impact on our DNA, and the expression of DNA. The primary effect of diet and lifestyle is on the variable expression of DNA. Not sure what you mean by "the impact on our DNA". Vague wording. I see you decided to use Google after all. Whats with the xxx's?
