Unformatted text preview: October 17, 2007 BS 110 EXAM #2 Review H-W Equilibrium P+Q = 1 to determine allele frequency P^2 + 2PQ + Q^2 to determine genotype frequency-- People (Darwin etc) are fair game; know what they did--Monophyletic means 1 group, & all members of the group evolve from a common ancestor-- Synapomorphy-- Sticky Capsule stages or types of bacteria; associated with parasitic hard to kill-- Endospores associated with freeliving; hard to kill with the human defense systems. Balanced Polymorphism when phenotypes occur (or are maintained) in the same percentages / proportions from one generation to the next (atypical we would not expect that) Disruptive (Diversifying) Selection if we start with a pop, through natural selection, the extreme phenotypes increase and the intermediate phenotypes decrease Ecotypes are distinct populations on a species. These populations are discontinuous. In contrast to a Cline graded change in a characteristic over a geographical distribution of...
