Question 1 of 5
Which condition must occur in order for identical (monozygotic) twins to develop?
Correct Answer: C
Rationale: The correct answer is C: One sperm fertilizes one ovum. Identical twins result from the fertilization of a single egg by a single sperm, leading to the formation of a zygote that later splits into two embryos. This process results in genetically identical individuals.
Choices A, B, and D involve multiple fertilization events, which would lead to fraternal (dizygotic) twins with different genetic compositions.
Therefore, the only condition that can lead to the development of identical twins is when one sperm fertilizes one ovum.
