Question
A. Use the genotype frequencies, relative fitness, and the mean relative fitness to calculate the genotype frequencies expected to be found in the next generation Show your work, include 3 decimals. p2’ = 2pq’ = q2’ = B. Is natural selection acting in this population in this new environment?
In the year 1849, an English naturalist, R.S. Eldeston, found that a population of Peppered moths (Biston
betularia) that usually showed white and light colors in their bodies (typica morph) suddenly started to show
darker colorations (carbonaria morph). This was thought to be an adaptation from the industrial revolution
that blackened the tree trunks of the moths' habitats. Suppose that this mutation is controlled by a single
diploid locus, with the light coloration allele (A) dominant over the dark coloration allele (a). In a wild
population of Peppered moths, there are 228 typica moths and 787 carbonaria morphs, for a total of 1015
peppered moths. You calculated the genotype and allele frequencies using HWE formula and wrote them
in the table.

In the following year, moth larvae of next generation were used as indicator of fecundity from the typica
and carbonaria morphs in the population. Based on the data, the relative fitness of each genotype was
determined as follows:
WAA= 0.68 WAa=0.68
Waa= 1
