In research done with fruit flies (but which may have implications for humans) scientists found that females are biologically primed to sense which males are more genetically compatible with them, and to make more eggs after mating with good matches than they do with less compatible matches. The findings suggest that females can somehow judge a potential mate upon first meeting and biologically react to boost the chances of producing successful offspring.
The study was detailed in the April 2009 issue of the journal GENETICS.
