Hybrid Mouse Resistant to Poison
Jennifer Viegas, Discovery News
Mice from different countries have likely interbred, producing what researchers call a “freaky” and “superior” house mouse that is resistant to a common rodent poison.
The discovery, reported in the journal Current Biology, demonstrates how hybridization can occur naturally among animals, yielding non-sterile individuals with beneficial attributes. In this case, the result is a mouse that is resistant to warfarin, a toxic and, usually, deadly ingredient in many rodent poisons.
