Answer :
Answer:
A, This is the case of selective pressure of environmental factors like snow, due to which favored the expression of the allele that formed white coat phenotype. This is not a Hardy-Weinberg principle, in which no selective pressure is applied. The relative frequencies of the alleles change in the gene pool, due to selective pressure, and the expressed alleles are often significant for survival in those conditions.
b,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.

Final answer:
Explanation of Hardy-Weinberg equilibrium and reasons for deviation in a wolf population.
Explanation:
Hardy-Weinberg Equilibrium: This genetic principle assumes five conditions: no natural selection, no mutation, no genetic drift, no gene flow, and random mating. Here are two reasons why a population might not be in Hardy-Weinberg equilibrium:
- Non-Random Mating: If individuals choose mates based on specific phenotypes, allele frequencies can change.
- Mutation: Introducing new alleles disrupts the equilibrium by changing allele frequencies.
Allele Frequency Change: In the wolf population scenario, migration will lead to a change in the population's genetic makeup as new alleles are introduced, altering allele frequencies over time.
