Some cows' infertility linked to Y chromosome

In the beef industry, if a cow does not get pregnant after breeding, she becomes an economic liability in the herd. Lack of calf production can significantly reduce annual revenue for producers.

Species conservation poised to benefit from DNA advances

A biologist at the University of York is part of an international team which has shown that advanced DNA sequencing technologies can be used to accurately measure the levels of inbreeding in wild animal populations.

Grazers and pollinators shape plant evolution

It has long been known that the characteristics of many plants with wide ranges can vary geographically, depending on differences in climate. But changes in grazing pressure and pollination can also affect the genetic composition ...
