You are right... for example in North Korea, the South Korean kids live better lifestyles and are giants compared to them. But nutrition isn't a big factor, my parents were raised eating foods fresh from farms, and I live in a town which has access to supermarkets.

Theres a non genetic theory that if you have older brothers, you are more likely to be gay http://www.dailymail.co.uk/health/article-173878/Boys-big-brothers-likely-gay.html

Assuming my mate is fully blonde. What would it be, 50%?

How does genetics play a role in when you start puberty and what your final height will be? My mom (5'7) and my dad (6'3) were both VERY late bloomers. I however, am 6'2 at 14 years old and I have no idea how I am... Any ideas?

I have light brown hair with occasional blond hairs in it. My mom has brown hair and a blonde brother and sister My dad has black hair and a blonde mother What are my chances of carrying the blonde gene?

Ok time for a punnet square:) DAD'S GENOTYPE (Red and blonde) RED ......| BLONDE| DARK....| BROWN |DARK Strwbry |BLONDE |BLONDE MOMS GENOTYPE (Dark and blonde) Overall, its a 25% chance the kid will be a strawberry blonde (Reddish-Blonde hair with freckles) 25% chance of brown (Dark or light) With freckles (has red hair gene) 25% chance of brown (Dark or light) Without freckles and 25% chance pure blonde Those with red hair gene may have reddish highlights in the sun and probably light skin and freckles sorry for crappy square..
