A new virus has been recently introduced to your snail population.  You think you’ve found a gene that confers resistance to the virus.  The gene has two allele variants in the population, such that homozygous recessive individuals are resistant to the virus.  You do a chi-square test to determine if there is evidence for selection favoring the gene of interest.  Your resulting chi-square value was: 2.91.  Which of the following statements is the most correct conclusion drawn from your results?   a. The null hypothesis that the population is in HWE is supported.   b. There is evidence for selection because the population appears to be in HWE.   c. There is not enough information to determine if the population is in HWE.   d. The null hypothesis that the population is in HWE is rejected.
