What happens to the genotypic frequencies from generation 1 to generation 5? 2.) What process is occurring when there is a change in genotypic frequencies over a long period of time? 3.) What would happen if it were more advantageous to be heterozygous (Ff)? Would there still be homozygous fish? Explain.
