Reduced sequence variability on the Neo-Y chromosome of Drosophila americana americana.

Genetics - 1 Sept 1999

McAllister B F, Charlesworth B

Abstract excerpt

Sex chromosomes are generally morphologically and functionally distinct, but the evolutionary forces that cause this differentiation are poorly understood. Drosophila americana americana was used in this study to examine one aspect of sex chromosome evolution, the degeneration of nonrecombining Y chromosomes. The primary X chromosome of D. a. americana is fused with a chromosomal element that was ancestrally an...
