2) The year is 2050. The climate has continued to warm. Areas in northern Canada and Alaska are without snow or ice; the average annual temperature has risen and previously snow-covered areas are now shrub land and some temperate forests. What effect would such a climatic change have on the gene pool of the rabbits? All BUT ONE could apply. 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. Choose one. A) The allelic frequency has most likely shifted to 85% GG and 15% gg. B) The dominant allele in the gene pool would become G, the previously rare allele. C) The allele for white, g, would be scarce and perhaps nonexistent in the population. D) White rabbits would be at a disadvantage in terms of camouflage and would likely fall prey to predators.

Transcribed Image Text:**Change in Rabbit Population 1850-2000**
This bar graph illustrates the changes in rabbit populations from 1850 to 2000, differentiated by coloration: white and gray rabbits. The vertical axis represents the percentage of the rabbit population, ranging from 0 to 100%.
- **1850:**
- **White Rabbits:** Comprised approximately 85% of the population.
- **Gray Rabbits:** Comprised about 15% of the population.
- **2000:**
- **White Rabbits:** Comprised about 30% of the population.
- **Gray Rabbits:** Comprised approximately 70% of the population.
There has been a significant shift in the population composition over this 150-year period, with gray rabbits increasing in population share, while white rabbits have decreased.
