Document Summary
People differ in many aspects of psychological functioning. For example, some people possess a (cid:862)t(cid:455)pe a(cid:863) perso(cid:374)alit(cid:455) a(cid:374)d are aggressi(cid:448)e, a(cid:373)(cid:271)itious a(cid:374)d (cid:272)o(cid:374)trolli(cid:374)g, (cid:449)hereas others possess a (cid:862)t(cid:455)pe b(cid:863) perso(cid:374)alit(cid:455) a(cid:374)d are passi(cid:448)e a(cid:374)d eas(cid:455)-going. Yet we are also similar in some aspects of our psychological functioning. For example, whether we live in the artic of tropics, we divide the color spectrum into similar colors. (ex: a strong bond between an infant and a mother). Behavioral genetics: the study of effects of environmental and genetic factors, and their interplay, on differences in psychological traits: genes: our codes for life, every cell in your body contains chromosomes- 23 donated from each parent. Each chromosome is made up of two strands of dna connected in a double helix. Identical twins develop from a single fertilized egg and are genetically identical, whereas fraternal twins develop from separate fertilized eggs and share half their genes, just like siblings.
