BIOL 522 Lecture Notes - Lecture 2: Genetic Admixture, Allele Frequency, Genotype Frequency
Document Summary
Allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences. Hw eq in 2 populations - p total = average frequency of allele in 2 populations. When dividing population into 2 subpopulations to the extent that p1 p t and p1 p2 then you see more homozygous individuals. F st = inbreeding within population -> reduction in heterozygosity compared to total population least 3 definitions where all end up mathematically equivalent, describes all these. Can help categorise when you have 2 populations how similar/ different they are. If you tend to mate with similar genetics, eg. associative mating, F st is not normally specified in terms of what definition they choose to use. F 2 ~ f st without the denominator, so it"s not like a correlation normalised by allele freq, it"s a variance but not exactly.
