This question has been confusing me for the longest time, but I never really made an effort to understand, so here I am.
I don't understand how I can be 99.9% identical to a friend when every physical feature between us is different. I have curly hair she has straight hair, I am 5'9 she is 5'5, I have brown eyes , she has hazel, I have smaller bones and less muscle and she has wider bones and a lot of muscle... how is our genetic data so similar ?
The DNA that we both have exact copies of, what does it code for ?
And I recently learnt that a polymorphic gene is a gene which has more than one allele in the population.. doesn't this mean that the 0.1% of genes that make us unique are all polymorphic ?
The gene that codes for eye colour is polymorphic , true ?
Is an example of the gene that is not polymorphic the gene that codes for RNA polymerase ?
