north american gray wolves usually have mixed gray and white fur, but some members of the species have a version of a gene, or gene variant, that gives them a mostly black coat instead. sarah cubaynes and her team studied twelve populations of north - american gray wolves. they found that the black - furred wolves are more common in areas where outbreaks of distemper virus happen regularly. the team also discovered that the black - furred wolves are more likely to be immune to distemper than the gray - furred wolves are. taken together, these findings suggest that ______
which choice most logically completes the text?
choose 1 answer:
a gray - furred wolves will soon replace black - furred wolves across north america.
b the gene variant that results in black fur may be linked to immunity to the distemper virus.
c north american gray wolves experience more outbreaks of distemper virus than other wolf species do.
d the average life span of gray wolves is likely to increase over time because of a particular gene variant.

Explanation:

The text states black - furred wolves are more common in distemper - outbreak areas and more immune to distemper. This implies a link between the gene for black fur and distemper immunity.

Answer:

B. the gene variant that results in black fur may be linked to immunity to the distemper virus.
