Q4-10- A large population of land turtles on an isolated island has tw.docx

Q4.10. A large population of land turtles on an isolated island has two alleles for a gene that determines shell thickness. The allele for thinner shells is dominant over the allele for thicker shells. The thinner-shell allele occurs at a frequency of 80% . Assuming there is no net advantage to thick or thin shells, what should the frequency of homozygous thicker-shelled turtles be in the population? (Hint: Use a population Punnett square to calculate the answer.)

1. Q4.10. A large population of land turtles on an isolated island has two alleles for a gene that
determines shell thickness. The allele for thinner shells is dominant over the allele for thicker
shells. The thinner-shell allele occurs at a frequency of 80% . Assuming there is no net advantage
to thick or thin shells, what should the frequency of homozygous thicker-shelled turtles be in the
population? (Hint: Use a population Punnett square to calculate the answer.)
