This unique relationship arises because identical twins share 100% of their DNA, making their offspring genetically equivalent to full siblings rather than cousins. While cousins typically share around 12.5% of their DNA, the children of identical twins inherit identical sets of genes from their parents, resulting in a closer genetic resemblance akin to that of siblings.
This fascinating genetic quirk blurs the traditional boundaries between cousins and siblings, highlighting the intricate genetic connections within families. Understanding this concept sheds light on the complex interplay of genetics and familial relationships, enriching our appreciation for the diversity and nuances of human kinship.
