Csp 161 lecture 8 biology (part 2) There will be 21 mc (leave one blank) There will be 9 fill in the blank (leave one blank) There will be 11 short answers(leave one blank) Behavioral genetics: study of genetic influences on behavior, behaviors are affected by both genes and environment, created by francis galton (cousin of darwin) Behavioral genetics methods: selection method the zeroth method. Defries (1978) study: selected two groups of mice into really active and not very active. Then, took the two most active and the two calmest and had them mate (the active mated with the active: did this process many times (30x, at the end, the last generation was 30x more active. In 6 minutes, the actives ones went the space of a football field. Conclusion: clearly the activity of mice has some genetic basis30 generations offspring 30x more active. Behavioral genetics methods: family method the first method. Trace family tree to determine heritable traits.
