Answer:
This observation might indicate that both groups form part of the same population (i.e., they have the same origin).
Explanation:
Perfect sequence homology in the gene associated with dark-colored fur might indicate that both groups of rock pocket mice form part of the same evolutionary unit, and thereby they share 100% sequence homology. Moreover, it is important to note that this information should be complemented with other observations and further molecular analyses to confirm that both groups form part of the same population.
