BIOLOGY 130 Study Guide - Midterm Guide: Insecticide, Winter Flounder, Kin Selection
Document Summary
Skittles game: variability exists among members of a population, some of that variation is heritable (transmitted genetically, individuals differ in the number of offspring they produce from parent to offspring). based on these traits. The animals worry about their own reproductive success i: cheating is favored, male infanticide benefits the individuals performing the behavior, not the population. Benefits of t: increased attractiveness to females, increased territory size, increased sperm production, increased metabolism, reduced survival, risk of injury or predation with fights. Artificial selection: intentional reproduction of individuals in a population that have desirable traits: difference disappears when reared in good/bad environment, it shows that selection has effects on population and the ability to modify forms. Knockout studies: artificially causes mutations and: target particular genes, and make them nonfunctional, inactivate gene of interest to examine effect on looks for effect development.
