Question

Quizplus · Accepted Answer

If a woman ovulates two oocytes and both are fertilized by two different sperm, two embryos will develop and result in fraternal (dizygotic) twins. Identical (monozygotic) twins occur when a single fertilized egg divides into two embryos. Siamese twins is an outdated and offensive term for conjoined twins, which is a rare occurrence and not necessarily related to ovulating two oocytes. Paternal twins is not a recognized term in biology.
