Question

Quizplus · Accepted Answer

Twins who develop from the splitting of a single egg that was fertilized by a single sperm are called monozygotic twins. This means that they are genetically identical and share the same DNA. Other terms for monozygotic twins include identical twins or maternal twins. Fraternal twins, on the other hand, develop from two separate eggs that were fertilized by two different sperm and may share up to half of their genetic material.
