The map shows the geographic distribution of salamander subpopulations that descended from the common ancestor E.e. oregonesis. Over millions of years, the salamanders moved south from what is now Oregon and northern California into areas to the east and west of California's Central Valley. The salamanders were initially separated by a large lake, and later by the unsuitable habitat of the Central Valley itself. Because of this geographic barrier, gene flow among some of these subpopulations is extremely limited, and in some cases has led to reproductive isolation.
Based on the salamander distribution data shown on the map, CHOOSE 2 salamander subpopulations between which gene flow can occur. Name them below in the short answer box.

Two subspecies of tufted-ear squirrels have been observed near the Grand Canyon. Scientists believe that these two squirrels evolved from a common population of squirrels that lived in the Ponderosa pine forests that once grew in what is now the Grand Canyon. The Kaibab squirrel is found on the north side of the canyon, and the Abert's squirrel is found on the south side. Which statement explains the formation of the two subspecies from the original population of tufted-ear squirrels?

Similar selection pressures on each side of the canyon caused fur color mutations to occur in the two populations.
As the canyon formed and the Ponderosa forestes disappeared, the original population was split into two isolated populations.
The original population was able to find simialr habitats in many small pockets of connected forestes reamaining around the Grand Canyon.
Natural land bridges connecting the two sides of the canyon allowed gene flow to occur between the populations after the Ponderosa forests disappeared.

I apologize for that. Here are the answers to the remaining questions:
1. The salamander subpopulations between which gene flow can occur are Salamanders C and E.
2. The two salamander subpopulations that would be least likely to reproduce successfully if brought together are Salamanders L and N.
3. The nucleotide sequences of the two species that are most closely related are B and D.
