Document Summary

Evolutionary psychology emphasizes evolutionary mechanisms that may help explain human commonalities in cognition, development, emotion, social practices, and other areas of behavior. Behavioral genetics interdisciplinary field of study concerned with the genetic bases of individual differences in behavior and personality. They are composed of dna and specify the structure of proteins. Chromosomes within every cell, rod- shaped structures that carry the genes. Each sperm and egg cell contains 23 chromosomes. Body cells contain 46 chromosomes arranged in 23 pairs. Dna chromosomal molecule that transfers genetic characteristics by way of coded instructions for the structure of proteins. 4 basic elements of dna: adenine, thymine, cytosine, and guanine (atcg) Genome the full set of genes in each cell of an organism (with the exception of sperm and egg cells). Genetic marker segment of dna that varies among individuals, has a known location on a chromosome, and can function as a genetic landmark for a gene involved in a physical or mental condition.
