Respuesta :
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.
Answer:
Because in the Hardy-Weinberg equilibrium, allele and genotype frequencies are supposed to remain constant, and in this population, they aren’t as some wolves have white coats and others don’t. This is caused by an allele that some wolves have and some don’t. The population’s second reason for not being in Hardy-Weinberg equilibrium is that some wolves have the advantage of having white fur, thus leaving the possibility for natural selection to take place.
