| All states and provinces had some level of introgression except Manitoba and Quebec. |
| This would rule out scenarios of numt evolution involving horizontal transfer or introgression between species. |
| In the absence of selection against genetic introgression, the incipient species should fuse. |
| The study showed populations from New York displayed the highest levels of introgression, followed by mid-Wisconsin and Tennessee. |
| Therefore, there is the potential for gene introgression across species via backcross of hybrid females to the parental species. |
| Such extensive archaic introgression, occurring on an almost global scale, was documented in a variety of different genetic systems. |
