Genetic regulation of avian sex determination

点击翻译按钮获取中文摘要

This project aims to enhance our understanding of gonadal sex determination (testis versus ovary development), using innovative genetic approaches that exploit the avian embryo as a model system. The project aims to define the key molecular events regulating gonadal sex determination in birds. It intends to enhance knowledge in the area of cell biology, embryology, and sex determination specifically. Importantly, it will have application to the poultry industry. Currently, half of all hatchlings (the undesired sex) are culled. The proposed project intends to illuminate those genetic pathways that can be targeted to produce single-sex lines of birds, a major goal of the multi-billion dollar Australian and global poultry industries.
