c. (3 pts) After spraying an insecticide the number of individuals of each genotype that survived is given below. Calculate the absolute fitness, and relative fitness of each genotype. Round up the answers to three decimal points. Number of individuals survived Genotype 50 AA 18 Aa 15 aa

Solution

c.

d.The selection coefficients for each genotype will be:s = 1-w ( w is relative fitness)

AA = 1- 1 = 0

Aa = 1- 0.36 = 0.64

aa = 1- 0.3 = 0.7

aa has the highest selection coeffecient which means that aa produces no viable offsprings and it has harder time than AA to produce viable offsprings.

Genotype	Number of individuals survived	Absolute fitness(It is the same as the number of individuals that survived and contribute to the next generation)	Relative fitness( Divide the number of individuals that survived with the highest fitness i.e 50)
AA	50	50	50 /50 =1
Aa	18	18	18/50=0.36
aa	15	15	15/50=0.3
