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:

Explanation:
The effects described are called phototropism, where light affects the direction of growth of the plant.
Auxin is a plant growth hormone that promotes growth of the plant by encouraging cell proliferation.
Light degrades auxin, so it is found more in the shaded side of the plant. This causes the cells in this region to proliferate more, and therefore there is more growth on the shaded side of the plant.
This causes the plant to bend towards the light.
