OxTalks will soon move to the new Halo platform and will become 'Oxford Events.' There will be a need for an OxTalks freeze. This was previously planned for Friday 14th November – a new date will be shared as soon as it is available (full details will be available on the Staff Gateway).
In the meantime, the OxTalks site will remain active and events will continue to be published.
If staff have any questions about the Oxford Events launch, please contact halo@digital.ox.ac.uk
A great deal of selection happens prior to birth, whereby many viable embryos do not make it to term. Antenatal selection is responsive to environmental factors and affects maternal and fetal health outcomes. Since male embryos tend to be more frail than their female counterparts, previous studies have used sex ratio at birth to establish that selection on the XY chromosomes exists prior to birth. However, the genetics of antenatal selection beyond the effects of XY chromosomes are not well understood. The challenge lies in the fact that many of the embryos which undergo selection are never observed. In this study we develop a novel approach to understanding the genetics of survival to term using within-family data.
