Question
Suppose a population has two alleles at a particular locus, and individuals with different diploid genotypes at this locus have
different probabilities of survival and expected offspring, as given in the table below:
Genotype
Percent surviving to adulthood
Expected offspring
GG
90%
11
Gg
80%
15
g8
50%
28
Calculate the absolute fitness, W, for each genotype, and then the relative fitness, w, using the smallest absolute fitness value
as your reference.
Assume that the selection differential s is equal to the difference between the relative fitness values for the heterozygote (Gg)
genotype and the genotype with the lowest fitness. (That is, s WG Wiowest ) If there are 410 individuals who are
homozygous for the G allele in a population of 1,177, and we ignore the effect of genetic drift, how much should the
frequency of the G allele change over one generation of natural selection?
Note that this asking for an overall size of change - you should report a value greater than 0. Compute your answer up to
four decimal places.
