Which two salamander subpopulations would be least likely to reproduce successfully if brought together? A Salamanders L and M
The map shows the geographic distribution of salamander subpopulations that
descended from the common ancestor Ecoregoneris 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
