Question

You are pushing a stroller that has two babies in it. one boy, dressed in blue, and one girl, dressed in pink. someone stops you tells you how beautiful your baby boy and girl are. then they ask if they are "identical twins." you tell them they are not, but what are you thinking?

Answer 1

Identical twins have exactly the same genotype, including sex.

It is not possible to have identical twins of various genders. Identical twins are all the time of a similar sex since they frame from a solitary zygote that contains either male (XY) or female (XX) sex chromosomes. Children boy/girl twins can't be identical twins. A lady's odds of having identical twins are not identified with age, race or family history.
