Question

In northern Canada a population of rabbits was predominantly white in color. The allele for white color is recessive while the allele for gray color is dominant. Over the last several decades, the average annual temperature of this area has increased and the long-term deposits of ice and snow have become scarce. This is an example of directional selection which tends to

Answer 1

Answer 2

Directional selection

Explanation:

This is an example of directional selection which tends to decrease genetic diversity

• Directional selection occurs when individuals homozygous for one allele have a fitness greater than that of individuals with other genotypes and individuals homozygous for the other allele have a fitness less than that of individuals with other genotypes
• Directional selection occurs when a single phenotype is favored, causing the allele frequency to continuously shift in one direction which decreases the genetic diversity
• When the environment changes, populations will often undergo directional selection, which selects for phenotypes at one end of the spectrum of existing variation
