They scanned the genomic data, trying to find genetic regions with strong links to selection by recent poaching and X-linked traits with recessive lethality, among other analyses. Abstract and Figures. process of eliminating less productive or less desirable cattle from the herd. The scientists noted that many in the herd have no tusks or smaller than usual tusks, which makes the animals less attractive to poachers. And because there were no records of male tuskless elephants, this inherited trait may be lethal to males. Keep in mind that there may be more than one plausible argument.
