The researchers also studied whether the same genetic variants were important for men and women. (sciencedaily.com)
They looked for similarities in such genetic variation among several thousand people with each illness and compared them to controls — calculating the extent to which pairs of disorders are linked to the same genetic variants. (sciencedaily.com)
Today's tigers show only 7 % of the same genetic variants that their ancestors did, meaning that 93 % of the genetic variation of the past has been lost, the researchers report online today, also in the Proceedings of the Royal Society B. (sciencemag.org)
