Female Antarctic seals give cold shoulder to local males

...s studies have shown that more genetically diverse individuals tend to be more resistant to disease, carry fewer parasites, and in the case of males, are more aggressive and father more offspring. It had long been assumed that the females were passive, simply mating with their nearest male. However, using pat...

Nanotechnology meets biology and DNA finds its groove
