Answer: Monozygotic (Identical) Dizygotic (Fraternal)
Explanation:
Monozygotic twins occur when a single egg is fertilized and it divides into two embryos, resulting in two embryos with the same genetic make-up.
Dizygotic twins occur when two eggs are fertilized by two sperms and implant in the uterus, resulting in two embryos with different genetic make-up.
