Question

Given the data below in a population of adolescent wolves where fur density is the trait.

DD = half of them survive
Dd = seventy percent survive
dd = ten percent survive

Prior to the cold season, in the first generation, DD = one thousand, Dd = three hundred, dd = seven hundred.

For each (e.g. DD, Dd, dd), determine its relative fitnesses. And, determine the anticipated allele frequencies in the following generation, given that the population total is one thousand in the second generation. SHOW ALL the calculations. Then, given that another population (not the same as the previous one) has a beginning “d” frequency of .2, produce an estimated graph showing the change in “D” and “d” allele frequencies as time passes. Provide an explanation. Specifically, the reason the estimated graph is in that particular shape. And, in this particular population, would you suppose the variability of genes be lost or would it be preserved as time passes? Explain the reasoning.
