Document Summary
60463080: no, because the population genetics definition of evolution is the change in allele frequencies observed in a population over generations. An individual alone cannot undergo evolution under this definition: the hardy-weinberg theorem is a null model of evolution. This phrase means that the h-w theorem is a model that predicts what expected allele frequencies should be when a population is not undergoing evolution (i. e. no evolutionary mechanisms are occuring). All genotypes equally likely to survive and reproduce. No alleles enter or leave population via migration gene flow. Selection: evolution can occur if one or more of these assumptions are not met, random mating is mating between individuals in a population with respect to the alleles at their genetic locus of interest. 1: a) population size = 4 shows some simulations" allele frequencies fixate or disappear. Population size = 40 shows less simulations" allele frequencies fixate or disappear.
