Question

also, according to tbe answer... if selection were the only mechanism of evolution acting on this population which genotype(s) would you expect to increase in frequency?

Question 13 2 points se Fecundity (offspring) Examine the data below and answer the following questions. (Same data as previous question) Genotype Probability of Survival | AA1 25% | A.AZ 60% A2A2 8596 Calculate the coefficient of selection for each genotype.

Answer 1

To calculate coefficient of survival first we need to calculate the survival X reproductive rate because the reproductive rate and the survival rate for each genotype are different in the given data and then we also need to calculate relative fitness of each by dividing each survival X reproductive rate with the highest survival X reproductive rate among the all genotypes.

Hence, according to data given in the question:

Genotype	A1A1	A1A2	A2A2
Probability of survival (survival rate)	25%	60%	85%
Fecundity (reproductive rate)	50	70	80
Survival X Reproductive rate	0.25/50=0.005	0.6/70=0.0085	0.85/80=0.010
Relative fitness (w)	0.005/0.010=0.5	0.0085/0.010=0.85	0.010/0.010=1.0

Coefficient of survival can be calculated by the following formula:

Coefficient of survival (s) = 1- w

Coefficient of survival for (A1A1) = 1.0-0.5=0.5

Coefficient of survival for (A1A2) = 1.0-0.85=0.5= 0.15

Coefficient of survival for (A2A2) = 1.0- 1.0=0.0
