22. Evolution of Populations

In the context of populations, how do we define evolution?

Allele frequencies can be altered by __________.

In the Hardy-Weinberg equation, p² represents __________.

In a large population of bonobos, the frequency of the recessive allele is initially 0.1. There is no migration and no selection. What is the frequency of the dominant allele? Assume that there are two alleles of this gene.
