Nutrition and lifestyle tends to play a pretty major role as far as both height and development goes, sometimes as much or even more than genetics.

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

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..
