TABLE 1 Observed (O) versus expected (E) mc1r genotypes of black bears (Ursus americanus) by landmass in coastal British Columbia, Canada (2012-2017). Monte Carlo Exact Chi-square p-values reflect results from tests for departures from genotype frequencies expected under Hardy-Weinberg equilibrium.

Use the values in "Table 1" to calculate the allelic and genotypic frequencies for each population. b. Show whether population 1 is in Hardy-Weinberg Equilibrium using the bear numbers above. c. These bears have been studied over a number of years and sampled a number of ways - results regarding HWE have varied. Use what you know about the 5 assumptions of HWE (hint: pick one) to propose one possible reason why the population of Kermode bears may not be/have been in HWE.
