When a fertilized egg splits or divides in half after conception, the result is fraternal twins.

Question

BlackTom AI · Accepted Answer

The statement presented asks whether a fertilized egg splitting or dividing in half after conception yields fraternal twins.
Option 1: True. This would claim that splitting a single fertilized egg results in fraternal twins. However, splitting the zygote creates identical (monozygotic) twins, not fraternal twins, because the two resulting embryos originate from the same fertilized egg and share nearly identical genetic material.
Option 2: False. This is the accurate assessment because when an embryo splits, the two individuals come from the same fertilized egg and end up genetically nearly identical, which characterizes identical twins. Fraternal twins arise when two separate eggs are fertilized by two separate sperm, leading to two genetically distinct individuals.
In contrast to fraternal twins, identical twins form when a single zygote splits; the concept of splitting after conception directly matches the mechanism of monozygotic twinning, not dizygotic twinning. Thus, the claim that splitting produces fraternal twins misstates the underlying biology of twinning.
