Why are identical twins mostly alike physically even though many of them don't eat same food, same lifestyle? They still end up havin same height, same shape and all.

By the way, I am also a twin but not identical.

thorpido:
Genetic codes.
As long as they are identical twins,they will reach same heights and almost same weights(+ or - 1 or 2kg).

You are a fraternal twin.Fraternal twins have different amniotic sacs and are from different eggs so they are not exactly alike though born same day.Identical twins come from the same egg.

My brother hustle o make ur pikin go serve abroad.

frowland:


Yea, I am a twin and know all about those stuffs and I also coincidentally have twin daughters as well. I think you are wrong on the other one.
What most likely happen is over time, they live same lifestyle, eat same type of food and all what not and ends up growing almost Identical in shape and size (I am not talking about similarities but shape and size)
You cannot tell me that if I seperate an identical twin from birth that after 20years will still have same body shape. That is impossible. What will be noticeable is the obvious lookalike like as if you are looking back in time when you are slim or fat.

thorpido:
If you separate them and put them in different environments,they will still look about the same size even after many years.The differences you will see will be negligible.eg if one is in Africa and the other abroad,the effect of the sun will make one slightly darker.However,no matter what they eat at different places,the weight will still be ALMOST same.

It's genetic coding,the environment will have just little effect.

They both look sooo plastic and fake! I can only imagine the stench that ooze from their fish tank..

The bold is totally false.
Genes do not 100% dictate destiny.
Have you heard about epigenetics?

frowland:


Impossible!!!!! Height will obviously be same but certainly NOT weight. So with your logic, if one likes Pizza and burger and all, and the other is in the village fetching firewood, they will have same weight?? You are certainly confused about my point.
I live with twins and I know their behavior. If one eats, the other will eat and vice versa. If one play, the other will play. Whatever you buy for one must be done for the other, they also sleep same time and wake same time! This makes them grow alike both in height and size.
But if I happen to separate them, I will change this routin which will in turn affect their growth pattern.
NASA experimented with two twins in one's year and the results was obvious.

thorpido:
Almost the same is the key phrase here.Their metabolism rate is going to be practically the same and what they store in their bodies will almost be equal at the end of the day.You won't have them with weights that are markedly different.

thorpido:
I have identical twins as friends.They have both been married for over 10yrs.Their weights are almost same Tell me,have their wives been giving them same meals?

Xisnin:

The OP was talking about phenotype.
Even Identical twins can have a wide difference in metabolic rate
and do have different weights.
It is not common but it happens.

Most of the common-sense assumptions we made fall flat when put under scientific scrutiny.
