Give two reasons that the wolf population is not a hardy-weinberg equilibrium.

 HW equilibrium means no selective pressures like the long, snowy winters selectively favoring the white coat phenotype over the other coat phenotypes. Selective pressures change the relative frequencies of the alleles in the gene pool. 
It also means the population does not have either immigration or emigration to change the ratios of alleles in the gene pool 

The Hardy-Weinberg principle of genetic equilibrium tells us what to expect when a sexually reproducing population has no selection pressure, no gene flow, no nonrandom mating, not even genetic drift.
