The fur color in a colony of mice has been brown for many generations. One gene appears to code for the fur color pigment. In a recent litter of mouse pups, one mouse was born with white fur. Which of the following could have caused this change in fur color?
A. a mutation in the DNA sequence of the gene for brown fur
B. recombination between genes for fur color
C. All of these choices are correct

A mutation in the DNA sequence of the gene for brown fur  

Explanation:

The mutations are capable of changing the encoded protein product, in this case the gene that encodes for the fur color pigment. This mutation may have occurred during mitosis or meiosis divisions.

If it is a spontaneous mutation that occurred in the germinal line (meiosis) and confers an adaptive advantage, it will increase their frequency in the population.

i think the answer is g1
