Question
In northern Canada, a population of rabbits was predominantly white in color. The allele for white color is recessive (g) while the allele for gray color is dominant (G). 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. In this case, the frequency of a previously rare allele becomes more frequent in the population.
 
 
What is the most likely genotypes of the population rabbits living in northern Canada in 1850, if G is the allele for gray and g the allele for white?
 
A) 85% g and 15% G
 
 
B) 85% gg and 15% Gg
 
 
C) 85% Gg and 15% Gg
 
 
D) 85% GG and 15% gg

**Change in Rabbit Population 1850–2000**

The bar graph illustrates the change in rabbit population from 1850 to 2000, categorized by the fur color of the rabbits: white and gray. 

- In 1850, white rabbits constituted approximately 85% of the population, while gray rabbits made up about 10%.
- By 2000, the percentage of white rabbits decreased to about 25%, whereas gray rabbits increased significantly, constituting approximately 80% of the population.

The y-axis represents the percentage of the rabbit population, ranging from 0 to 100%. The x-axis distinguishes between the two years, 1850 and 2000, and the two categories of rabbit fur color. This data suggests a significant shift in the population dynamics of rabbits over the 150-year period.
