chance effects random genetic drift populations are not infinitely large reproduction is a probabalistic process the number of offspring is different by chance genes in one generation are represented by a chance number of copies of the gene in the next Stochastic changes in populations random genetic drift simple model - assumptions monoecious diploid organisms allows for self-fertilization sexual reproduction random genetic drift simple model - assumptions non-overlapping generations no mutation no selection random genetic drift simple model - assumptions some genes represented more some genes represented less some represented as same number

random genetic drift simple model - assumptions rate of genetic drift depends on the size of the population - 2N genetic drift faster when N is smaller Hartl & Clark, 1989 simulation results Hartl & Clark, 1989 random genetic drift simple model - assumptions Many independent subpopulations each of constant size N random mating within each subpopulation initial base population - infinite size initial base population - infinite size GAMETES 2N 2N 2N 2N 2N 0 GEN
