A team led by the Doñana Biological Station – CSIC has compared the deleterious mutation burden in Iberian and Eurasian lynxes. The study shows that populations that have been small their whole history, such as that of the Iberian lynx, may be more tolerant to the genetic effects of the increasing kinship between progenitors after a sudden reduction in population size. The team has also created a catalog of deleterious variants in the Iberian lynx that will help to minimize the...
