Document Summary
Population: a group of individuals of the same species living in the same place at the same time. Individuals in a population are more closely related than members of other populations. Population genetics: a study of the genetic makeup of populations over time. Easy to study the phenotype of organisms/populations. Random events, may create new alleles that can be useful or harmful. Much more effective in increasing variation in organisms with short life spans (e. g. , bacteria) More effective in organisms with longer life spans. Gene pool: all the alleles in a population at one time. Example: flower population with two morphs: dominant red (r) and recessive white (r). 80% of loci contain (r), 20% contain (r). P represents the proportion of the dominant allele, and q = the proportion of the recessive allele. p = 0. 8, q = 0. 2, p + q = 1.
