Suppose a population of organisms is in Hardy–Weinberg equilibrium with respect to a gene that has two alleles, Y and y. The
YY genotype has a frequency of 0.11, the Yy genotype has a frequency of 0.44, and the y genotype has a frequency of 0.45.
Calculate the frequency of each allele to two decimal places.
Y allele frequency:
y allele frequency:
Consider a gene with two alleles, C and M. The table below describes fitness for different genotypes in two populations.

Assume that both populations begin with frequencies of 0.5 for each allele, population size is infinite, and there is no migration between populations. Would you predict that either allele would become fixed in either population?
