  2. Outline 1. Genes 2. Evolutionary Psychology 3. Behavior Genetics 4. Environmental Influence 5. The Nature and Nurture of Gender

  3. I. Genes: Our Biological Blueprint Genes enable our biology, which in turn enables our behavior • Chromosomes • DNA (deoxyribonucleic acid)

  4. I. Genes: Our Biological Blueprint • Genes • Genome

  5. Nucleus Chromosome Gene Cell DNA I. Genes: Our Biological Blueprint

  6. II. Evolutionary Psychology Study of how natural selection favored behavioral tendencies that contribute to the survival & spread of our ancestors genes. • A. Natural Selection

  7. II. Evolutionary Psychology • B. Mutation

  8. II. Evolutionary Psychology • C. Sexuality: Our natural yearnings are our genes’ way of reproducing themselves • Gender

  10. III. Behavior Genetics Study individual differences weighing genetic & environmental contributions to our various traits. A. Twin Studies • Identical Twins: • Fraternal Twins:

  11. Identical twins Fraternal twins Same sex only Same or opposite sex III. Behavior Genetics

  12. III. Behavior Genetics • Twin Studies: • Identical twins • Separated Twins –
