Question

(Continued on page 2) Now, you want to predict how the composition of the lupin population will change over time due to natural selection. 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) w (0878)(0.878)(1 )1-1(2)(087800.122 )(1)1+ 1(Q 122)(0.122)(06671 0.771+0.214 +0.00993 0.995 4) Next, use the current genotype frequencies, relative fitness and the mean relative fitness to calculate the three significant figures, Show your work. (0.67 pts each, total 2 pts) genotype frequencies expected to be found in the next generation. Show the answer in 1(0.878)(o.878 1)1/0.9950.775 1(0,12210.12210.667)/0.995-0.00998 s) Which phenotype of the flower color does natural selection favor in this environment? How can you tell? (1

Explanation / Answer

From the given data,

the new genotypes after natural selection is, p2 = 0.775 ; 2pq=0.215 ; q2 =0.00998.

Therefore total frequency of allele for phenotype1 = 0.775+0.215.

= 0.990

and for phenotype 2 =0,00998

Assuming the phenotype to be AA and Aa the dominant colour of flowers in the total population of flowers given.

Phenotype 1 which is dominant will be selected.
