BIO 4113 Lecture Notes - Lecture 8: Genotype Frequency, Allele Frequency, Genetic Drift
Document Summary
Evolution (darwin) - change in populations from one generation to the next. Evolution (modern synthesis) - natural selection with mendelian genetics change in allele frequencies in populations from one generation to the next. Population genetics - the study of alleles in populations and the causes of allele frequency changes. Lactose is for babies except for the fact that we domesticated cows. We have an allele that results in a developmental breakdown and lactase is being produced through all of your stages in your development. This makes it so that we can break down milk. This has happened in independent populations of humans across the globe (lactase persistence) Natural selection and genetic drift are the most effective in changing populations. P + q = 1 (q = 1 - p) An alleles frequency can be used to estimate the probability that it will be sampled at random from a population. If allele frequencies are known, you can predict future genotype frequencies.
