| It is possible that the inland plants Hodgdon called variety typica represent introgressive hybrids between L. pulchella and L. intermedia. |
|
| For instance, introgressive events, even when rare, may be more important than mutations as a source of novel genetic variability within taxa. |
|
| Because hybrids are usually fertile, they can often produce introgressive hybrids with the parental species or triple hybrids with another taxa. |
|
| Incongruence among data sets can arise from various biological processes, including introgressive hybridization, recombination, and gene conversion. |
|
| This area sympatry comprises a limited zone of introgressive hybridisation in the Gulf of St. Lawrence, the Laurentian Channel and Flemish Cap. |
|
| Of the 14 populations studied, only the Mbuti Pygmies possessed all three introgressive variants. |
|
| Bidirectional introgressive hybridization between a cattle and human schistosome species. |
|
| But hybrid zones imply much more through introgressive hybridization where hybrids backcross with parental species. |
|
| Ultimately, introgressive hybridization may lead to the occurrence of a hybrid swarm, raising questions as to the species' identity. |

| Speciation via introgressive hybridization in East African cichlids. |
|
| Limited realized dispersal and introgressive hybridization influence genetic structure and conservation strategies for brown rockfish Sebastes auriculatus. |
|
| Introgressive hybridisation appears to be a key factor in the determination of population genetic structure of S. fasciatus and S. mentella. |
