Dance Your PhD Finalists 2013

Females of the red jungle fowl mate with multiple males, which can create competition between sperm of different males in order to fertilize the egg. In my PhD thesis, I explored the effect of brotherhood on sperm competition and female choice. Interestingly, the brother of the first male that the female has mated with invests more sperm in the female than the non-brother of the first male mate. However, the female ejects a higher proportion of sperm from the brother of the first mate and favours the sperm of the non-brother, facilitating a higher fertility by the non-brother’s sperm ... Inspired by various sports, the dance movements in this video reflect the competitive nature in the sperm world.
Every year, Science's Dance Your PhD competition challenges grad students past and present to convey their dissertations with interpretive dance.
