 [mon″o-zi-got´ik; mon″o-zi´gus] (monozygous) pertaining to or derived from a single zygote (fertilized ovum); said of twins. See also dizygotic.
A, Monozygotic twinning. The single inner cell mass divides into two inner cell masses during the blastocyst stage. These twins have a single placenta and chorion, but each twin develops in its own amnion. B, Dizygotic twinning. Two ova are released during ovulation, and each is fertilized by a separate spermatozoon. The ova may implant near each other in the uterus, or they may be far apart. From McKinney et al., 2000.
