monozygous
From one zygote
Monozygous means derived from a single fertilized egg.
Monozygous twins—more commonly called identical twins—develop when one zygote splits into two embryos, producing siblings with the same genetic makeup.
The term appears primarily in medical and scientific contexts: The study compared monozygous and dizygous twin pairs.
