Understanding evolution - guide for teachers
A very cool simulation showing how random forces cause either fixation or loss of any new allele that appears in the population. Note that when the initial frequency of the new allele (p) is low (say, 0.1) and the population size (n) is large, then the chances of the allele being fixed are slim.
