Whip-poor-wills. (Camprimulgus vociferus! Thepopulation has found in two adult phenotypes: rufous(red) and gray.An ornithologist investigates the genetics of this color variationand discovers that rufous individuals are one of two genotypes (RRor Rr), while gray individuals are rr. The frequency of thesegenotypes at Generation 1 in northern New Jersey are: 60% RR,20%Rr, and 20% rr.
1. If the Hardy-Weinberg Law holds for these genetic variants,what is the frequency of the R allele in this population?
(A) 0.3
(B) 0.4
(C) 0.5
(D) 0.6
(E) 0.7
2. What will the phenotype frequency be in the next generation(Generation+1)?
(A) 60% rufous, 40% gray
(B) 80% rufous, 20% gray
(C) 51% rufous, 49% gray
(D) 91% rufous, 9% gray
(E) 49% rufous, 51% gray
3 What will the dominant allele frequency be in the generationafter Generationt+2 ?
(A) 0.3
(B) 0.4
(C) 0.5
(D) 0.6
(E) 0.7
