On 28th November OxTalks will move to the new Halo platform and will become 'Oxford Events' (full details are available on the Staff Gateway).
There will be an OxTalks freeze beginning on Friday 14th November. This means you will need to publish any of your known events to OxTalks by then as there will be no facility to publish or edit events in that fortnight. During the freeze, all events will be migrated to the new Oxford Events site. It will still be possible to view events on OxTalks during this time.
If you have any questions, 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.
