What is produced when identical twins separate during early development?

When identical twins separate during early development, the result is two identical twins. This occurs during the process of cleavage in the early stages of embryonic development. Identical twins, also known as monozygotic twins, originate from a single fertilized egg that splits into two separate embryos. Since both embryos come from the same genetic material, they share the same DNA, making them genetically identical. This is distinct from fraternal twins, which arise from the fertilization of two different eggs with two different sperm, leading to genetically unique siblings. Thus, the correct answer accurately reflects the biological process involved in the formation of identical twins.
