Identical twins can have which of the following?A) Diverse hereditiesB) Dizygotic originC) Identical phenotypesD) The same genotype

Varshi Sridhar · Accepted Answer

Final Answer : D, Explanation :  Identical twins come from a single fertilized egg that splits into two embryos, so they have the same genotype. They may have slightly different phenotypes due to environmental factors, but their genetic makeup will be identical. A) is incorrect because identical twins come from the same egg and sperm, so they have the same heredity. B) is incorrect because identical twins come from a single fertilized egg, while dizygotic or fraternal twins come from two separate eggs fertilized by two separate sperm. C) is partially correct, as identical twins do have identical phenotypes for many traits, but they may have differences due to environmental factors or new mutations that arise after the split of the fertilized egg.

Identical twins can have which of the following?

A) Diverse heredities
