Document Summary
15: population genetics study of genetic makeup of gouger of individuals and how that structure changes over time ( evolves ) Mendelian pop - a group of interbreeding, sexually reproducing individuals that have a common set of genes. Allelic frequencies: genotypic frequencies, proportion of a particular genotype. N = total # of individuals the sum of all genotypic sequences always equals 1: allelic frequencies: = # of copies of the alleles / # of copies of all alleles at the locus: from number of genotypes, from genotypic frequencies ( p + q = 1 ) Mathematical model that evaluates the effect of reproduction on genotypic and allelic frequencies. A set of assumptions and two predictions. Must have: large pop. , random mating, and no mutation, migrations, nor natural selection. Genotypic frequencies stabilize after one generation in proportions: When conditions are met, reproduction does not alter allelic or genotypic frequencies and allelic frequencies determine frequencies of genotypes.
