Justify whether the statement “the average fitness of a population can either increase or decrease due to gene flow” is true or false. Introduction: Gene flow or gene migration is caused due to the immigration or emigration of an individual to a new habitat or to a new environmental location and causing an alteration in the allele frequency. It is a mechanism of genetic diversity transfer among the population, which changes the distribution of the alleles and thus disturb the genetic equilibrium of any area.

Consider a gene with two alleles, C and M. The table below describes fitness for different genotypes in two populations. Fitness CC CM MM Population 1 1.0 1.0 0.6 Population 2 0.9 0.9 1.0 Assume that both populations begin with frequencies of 0.5 for each allele, population size is infinite, and there is no migration between populations. Would you predict that either allele would become fixed in either population?

Fitness CC CM MM Population 1 1.0 1.0 0.6 Population 2 0.9 0.9 1.0 Assume that both populations begin with frequencies of 0.5 for each allele, population size is infinite, and there is no migration between populations. Based on the table, how would you expect the frequency of M to change over time in population 1? A.) frequency of M will increase B.) frequency of M will decrease C.) frequency of M will stay the same D.) frequency of M will change randomly
