Document Summary

Mendelian genetics in populations i: selection and mutation as mechanisms of. Mendelian genetics in populations: the hardy-weinberg equilibrium principle: population genetics begins with a model of what happens to allele and genotype frequencies in an idealized population. Juveniles grow up to become the next generation of adults. The 34 aa adults together make a total of 340 games: 340 carry allele a and none carry allele a. The 57 aa adults together make a total of 570 gametes: 285 carry allele a and 285 carry allele a. The frequency of gametes in the new gene pool is 0. 625 for allele a and 0. 375 for allele a. In simulated populations allele frequencies change somewhat across generations. This is evolution resulting from blind luck: blind luck causing populations to evolve unpredictably is an important, this mechanism of evolution is called genetic drift. result of population genetics.
