Document Summary
Define what we mean by migration (from an evolutionary vs ecological perspective) Understand the hardy-weinberg equilibrium, as well as the assumptions of it. Describe the island model, as well as the basic population genetic equations associated with gene flow in this model. Discuss how and why the strength of selection is important relative to amount of gene flow. Explain why populations is an important consideration for gene flow. Movement of individuals followed by mating or movement of gametes followed by fertilization. In plants it"s more common for pollen to move (gametes) In vertebrates, the individuals can move around itself. Immediate change in p in the recipient population. Pa and pa -> allele frequencies at the locus. Together, have to sum to 1 p + q = 1. May 15 p = pa q = 1-pa. Allele frequencies give an expectation of what proportions of genotypes they should have.
