Forest logging removes trees leaving behind only smaller bushes. Some rats in a depleted forest have an allele that makes them smaller than normal rats, it is easier for the small rats to hide from predators in the bushes. How will the allele frequency change in the rat population and has genetic diversity helped or hurt the survival of the rat population ? Explain
