Suppose a population has two alleles at a particular locus, and individuals with different diploid genotypes at this locus havedifferent probabilities of survival and expected offspring, as given in the table below:GenotypePercent surviving to adulthoodExpected offspringGG90%11Gg80%15g850%28Calculate the absolute fitness, W, for each genotype, and then the relative fitness, w, using the smallest absolute fitness valueas 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 arehomozygous for the G allele in a population of 1,177, and we ignore the effect of genetic drift, how much should thefrequency 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 tofour decimal places.
