Question
1) What are the implications for the genetic structure of polutations when Hardy-Weinberg law is in effect? Choose all that apply.
A) Allele, but not genotype frequencies, can change over time.
B) When the two alleles in the population are equal, the frequency of homozygotes is maximized.
C) Reproduction alone can bring about evolutionary change.
D) A single generation of random mating produces the equilibrium frequencies of p2 ,2pq, and q2.
E) Genotype frequencies are determined by allele frequencies.
2) When both natural selection and mutation are occuring in a population, what is the result?
A) Selection always removes deleterious mutations as fast as they are added to a population.
B) Selection is a stronger force than mutation and so an equilibrium is reached depending on the pattern of selection in the population.
C) Mutation always introduces alleles into a population and so an equilibrium is reached depending on the rate and type of mutations in the population.
D) An equilibrium is reached where the number of alleles added by mutation is balanced by the number of alleles removed by selection.
E) Selection and mutation are different evolutionary forces and so do not affect one another.
