Surviving Chromosomal Rearrangements

Surviving Chromosomal Rearrangements

Last blog I talked about the Transcaucasian mole vole. This little burrowing mammal has lost its Y chromosome over time. Now both males and females have only a single X. I focused on how scientists can't yet figure out how there are any male mole voles running around. This week, I want to focus on what this means from an evolutionary perspective.
