Unit 3-C (B):Twin Studies Mr. McCormick A.P. Psychology
Do-Now(Discussion) • Think about someone you know who was adoptedas a child: • In what ways are their personalitiessimilar to their adoptive parent(s)? In what ways are they different? • In what ways are their personalitiessimilar to their biological parent(s),if known? • What do you feel has a greater influence on one’s personality – one’s biological make-up or one’s familial environment?
Identical Vs. Fraternal Twins • 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
Separated Twins 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.
