Document Summary
Assumptions (again) -> for hardy weinberg equilibrium: no natural selection on that locus, no mutation, no migration, population size is large and has no random effects, mating is random with respect to that locus. Mutation: happens continuously, when there is mutation you are able to predict changes that may occur under the frequency of an allele. The probability of a mutation happening is relatively low, but doesn"t do anything for the fitness of the allele. In the absence of selection, mutation causes very slow change in allele frequencies at particular loci. > if change of mutation is happening at a faster rate it tells you that there is selection happening. Selection can make things move much faster-> salt test on fruit flies. Results of test: all original inbred stock all died, the survival rate for the salt tolerant flies was greater than all others.
