Title: Recent Advance in Genes of Avian Sex Determination and Differentiation
Abstract: At present, the mechanism of avian sex determination remains unknown. There are several hypotheses. The one is W sex chromosome carries a dominant ovary-determining gene. The second is Z-chromosome has a dosage mechanism (one Z for female, two Z for male). The third possibility is that both mechanisms operate. This article mainly reviewed three promising candidate genes located on the sex chromosome. The Z-linked gene, DMRT1, supports the Z-dosage model of avian sex determination. Two novel W-linked genes, ASW and FET1, represent candidate female determinants. Besides, this article also discussed some genes related to avian sex determination and differentiation, i.e. SOX9, AMH, cFOXL, CYP19A1.
