Document Summary
Variation not determined by how many heterozygotes, but by how many are expected under hardy-weinberg equilibrium: he = expected heterozygosity. Measuring divergence with inbreeding coefficient: 2pq = 0. 42. Inbreeding in sub-populations is relative to the total population o: example: Overall he = 0. 5 heterozygote frequency we: fst = 1 (0. 18/0. 5, = 0. 64. Movement of individuals from one population to another: ex. Population on an island off the coast of a large continent. In evolutionary terms, refers to movement of individuals between populations: different from the founding of new populations. Migration rate = 0. 2: proportion of population the immigrates from continent, on continent: p = 0. 0 (mainland) to the island each generation. Assume this p stays constant: on island: p = 1. 0 immigration. Assume this is starting p, and will change with. Ex. p = 0. 8; pm = 0. 0; m = 0. 2. Migration and selection in lake erie example. Mainland all snakes have banded markings: p.
