Answer:
Identical, or monozygotic (MZ), twins have the same genetic makeup and Fraternal, or dizygotic (DZ), twins share 50% of their genes.
Step-by-step explanation:
Identical, or monozygotic (MZ), twins have the same genetic makeup. Rather than developing into one individual, the fertilized egg cell splits and develops into two individuals with the same genetic makeup. The Fraternal, or dizygotic (DZ), twins share 50% of their genes, meaning that they have different genetic traits.
