A population of bed bugs has invaded Building A. A studentsampled this population and estimated the following phenotypicfrequencies (which were caused by a single gene with two alleles: Band b; you don’t want to know how this undergrad determined thephenotypes of these bed bugs in this population).

i. 11% aggressive blood suckers (BB)

ii. 26% moderate blood suckers (Bb)

iii. 63% weak blood suckers (bb)

If this population were to reach Hardy-Weinberg equilibrium inone generation, what would the phenotypic frequencies be in thatnew generation? Application of an insecticide throughout Building Adifferentially impacts these three genotypic classes. The fitnesscoefficients in the presence of insecticide are: wBB = 0.9; wBb =0.5; and wbb = 0.1. What would be the expected phenotypic ratios ofbed bugs in the next generation following insecticide treatment? Doyou think this application of insecticide should be continued orterminated?

Please answer ALL parts of the question and I will be sure to"thumbs up" your response! Thank you!

What parts do all plants have, and what parts do only some plants have?

The B locus has two alleles B and b with frequencies of 0.8 and 0.2, respectively, in a population in the current generation. The genotypic fitnesses at this locus are w_BB= 1.0, w_Bb = 1.0 and w_bb = 0.0.

a.) What will the frequency of the b allele be in the next generation?

b.) What will the frequency of the b allele be in two generations?

c.) What will the frequency of the b allele be in two generations if the fitnesses are: w_BB= 1.0, w_Bb = 0.0 and w_bb = 0.0.

d.) Why is the difference between answers in parts b.) and c.) so large?
