Preservation of the Y transcriptome in a 10-million-year-old plant sex chromosome system.

Current biology : CB - 13 Sept 2011

Bergero Roberta, Charlesworth Deborah

Abstract excerpt

Classical genetic studies discovered loss of genes from the ancient sex chromosome systems of several animals (genetic degeneration), and complete genome sequencing confirms that the heterogametic sex is hemizygous for most sex-linked genes. Genetic degeneration is thought to result from the absence of recombination between the sex chromosome pair (reviewed by [1]) and is very rapid after sex chromosome-autosome...
