Identical Twins:

Twins who develop from a single fertilized egg that splits in two, creating genetically identical organisms

Same sex only

Fraternal Twins:

Twins who develop from separate fertilized eggs

Genetically no closer than brothers and sisters, but they share a fetal environment

Same or opposite sex


Identical twins who have been separated since birth tend to share many cognitive, behavioral, and
social similarities with one another (more so than fraternal twins).

Adopted children tend to share many cognitive,
behavioral, and social similarities, with both their
adoptive and biological parents; however, there tend to be stronger similarities with biological parents .
