WebIf a particular genotype produces only 65 percent viable young, its selection coefficient is: s = 1 - 0.65 = 0.35. The selection coefficient is used by researchers to calculate the rate at … WebBalancing selection refers to a number of selective processes by which multiple alleles (different versions of a gene) are actively maintained in the gene pool of a population at frequencies larger than expected from genetic drift alone. Balancing selection is rare compared to purifying selection. [1]
