Twins resulting from the fertilization of separate ova by separate sperm cell are called:

  • A. Paternal twins
  • B. Maternal twins
  • C. Fraternal twins
  • D. Identical twins
Correct Answer: C

Rationale: The correct answer is C: Fraternal twins. Fraternal twins result from the fertilization of separate ova by separate sperm cells, leading to siblings who share 50% of their genetic material. This is different from identical twins (choice D), which result from the fertilization of a single egg by a single sperm cell, leading to siblings who share 100% of their genetic material. Choices A and B are incorrect as they do not accurately describe the process of fraternal twinning. Paternal twins (choice A) and maternal twins (choice B) are not commonly used terms in genetics to describe types of twinning.
