Observation of a ZZW female in a natural population: implications for avian sex determination.

Proceedings. Biological sciences - 7 May 2004

Arit D, Bensch S, Hansson B, Hasselquist D, Westerdahl H

Abstract excerpt

Avian sex determination is chromosomal; however, the underlying mechanisms are not yet understood. There is no conclusive evidence for either of two proposed mechanisms: a dominant genetic switch or a dosage mechanism. No dominant sex-determining gene on the female-specific W chromosome has been found. Birds lack inactivation of one of the Z chromosomes in males, but seem to compensate for a double dose of...
