Under female control: egg defence, adaptive sex allocation, and sperm selection

点击翻译按钮获取中文摘要

Sexual conflict is prevalent at the gametic level, and females may respond to sperm competition via fertilisation barriers that mediate sperm entry. Surprisingly, the extent of female control over fertilisation is unknown, and the specific mechanisms that females utilise to manipulate fertilisation events are poorly understood. This project will combine innovative investigations that utilise whole organisms and in vitro fertilisation technology to study their gametes in isolation. The project offers pioneering work on gametic interactions that have not previously been characterised. It will extend knowledge on the mechanisms that underpin successful mammalian fertilisation and provide critical insight into the etiology of infertility.
