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 20%. 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.)o 4% o 16%o 50%o 64%
