A population of clams is being studied at the PrlQ gene to determine if the population is evolving with
respect to that gene. The following genotypes have been observed out of a sample of 501 clams: QQ
= 61, Qq = 202, and qq = 238 . The HWE expected genotype values for this population are as
follows: QQ = 52, Qq = 219, and qq = 229, with a calculated Chi - squared value of 3.096 .
The Chi - squared significance cut - off value is 3.841 . Based on these data and what is expected
under Hardy - Weinberg Equilibrium, what can we say about this population regarding the PrlQ gene?
a. The population is likely evolving, and likely selecting for homozygous recessive clams.
b. The population is likely evolving and is in Hardy - Weinberg Equilibrium.
c. The population is likely not evolving and is in Hardy - Weinberg Equilibrium.
d. The population is likely not evolving, as the homozygous dominant clams are being selected against.
