Sperm DNA and sex chromosome differences between two geographical populations of the creeping vole, Microtus oregoni. Academic Article

abstract

• The relative DNA content of the "O" and Y chromosome-bearing sperm is presented for the creeping vole, Microtus oregoni. The animals had been trapped in Oregon and in Washington State. The two populations had very similar autosomal chromosome relationships but differed greatly in the size of their X chromosome (which is not carried by vole sperm) and in their Y chromosome. The greater size and banding differences of the Y chromosome of the Washington State vole compared to the Oregon vole paralleled the greater differences in sperm DNA between the Y-bearing sperm and the sperm carrying no sex chromosome (O). The actual DNA differences between O and Y sperm was 12.5% for the sperm from the Washington State voles and 9.1% for sperm from the Oregon voles. The difference in sperm DNA content (12.5%) for Washington State voles was far greater than the difference shown for other voles or other mammals.
