In the question above you found the number of mutations in the gorilla genome if mismatches could not be repaired. In some circumstances, proofreading mechanisms are faulty and only remove 90% of mismatches before DNA replication moves on. How many mutations would you expect to see in the genome of a gorilla with a faulty proofreading mechanism?

You are conducting research on a tree lizard population in Arizona and found that the lizards leg length is controlled by a single gene where dominant S1 allele and recessive S2 allele code for long or short hind legs, respectively. Table below shows the current and expected future genotype frequencies in this population:   Genotype Current frequencies Expected future frequencies S1S1 0.705 0.690 S1S2 0.225 0.215 S2S2 0.070 0.095 Based on these numbers, which phenotype of tree lizards will be favored by natural selection if the environment doesn’t change in future generations?

Wild type blue-eyed Mary has blue flowers. Two genes control the pathway that makes the blue pigment: The product of gene W turns a white precursor into magenta pigment. The product of gene M turns the magenta pigment into blue pigment. Each gene has a recessive loss-of-function allele: w and m, respectively. A double heterozygote is self-pollinated. What proportion of offspring will be white?
