GIVEN: A wildflower native to California, the dwarf lupin ( Lupinus nanus ) norm

Question

GIVEN: A wildflower native to California, the dwarf lupin (Lupinus nanus) normally bears blue flowers but occasionally bears pink flowers. Flower color is controlled by a single diploid locus, with the blue allele (B) completely dominant over the pink allele (b). In a wild population of lupins, there are 50 pink lupins and 3291 blue lupins, for a total of 3341.

Relative fitness: ?BB= 1                    ?Bb= 1                   ?bb= 0.667

q2= 50/3341 = .015

Frequency of allele bassuming Hardy-Weinberg equilibrium:

q =.122

Frequency of allele Bassuming Hardy-Weinberg equilibrium:

p = .878

Genotype frequency of BB assuming Hardy-Weinberg equilibrium:

p2= .77

Genotype frequency of Bb assuming Hardy-Weinberg equilibrium:

2pq = .214

3) First, calculate the mean relative fitness of the parental population using the provided relative fitness and genotype frequencies that you calculated above. Show the answer in three significant figures. Show your work (1 pt)

4) Next, use the current genotype frequencies, relative fitnessand the mean relative fitnessto calculate the genotype frequencies expected to be found in the next generation. Show the answer in three significant figures. Show your work. (0.67 pts each, total 2 pts)

p2’ =

2pq’ =

q2’ =

Please answer number 3 and 4, and show work. Thank you!
