1) Use this table to calculate the genotypic frequencies in the F1, in response
to selection. 2) Which genotype is favored? Will the 'a' allele be lost from this population? 3) What will be the final gene frequency of p, if this selection continues? 4) Selection cannot perfectly adapt an organism to their environment, because
selection cannot maximize growth and reproduction at the same time. Explain,
relating the components of fitness to finite energy budgets. 5) Distinguish between directional and stabilizing selection. 6) Which type of selection is responsible for speciation?Population Genetics II
