Chapter 16 - Mader Biology
Hardy-Weinberg principal - allele frequencies should stay constant unless something causes them
to change.
dominance heirarchies - a higher-ranking animal has greater access to resources than does a
lower-ranking animal
disruptive selection - favors individuals at both extremes of the phenotypic range
allele frequency - Number of times an allele occurs in a gene pool
assortative mating - The selection of a mate based on similarity of traits
bottleneck effect - A change in allele frequency following a dramatic reduction in the size of a
population
cost-benefit analysis - way of thinking about a choice that compares the cost of an action to its
benefits
cystic fibrosis - An inherited life-threatening disorder that damages the lungs and digestive
system.
directional selection - shift of a population toward an extreme version of a beneficial trait
female choice - Females respond to some aspect of male phenotype
fitness - Ability of an organism to survive and reproduce in its environment
