A Statistical Approach for Distinguishing Hybridization and Incomplete Lineage Sorting

The American Naturalist, 2009
The extent and evolutionary significance of hybridization is difficult to evaluate because of the difficulty in distinguishing hybridization from incomplete lineage sorting. Here we present a novel parametric approach for statistically distinguishing hybridization from incomplete lineage sorting based on minimum genetic distances of a nonrecombining ...

Transgenerational selection driven by divergent ecological impacts of hybridizing lineages

Nature Ecology & Evolution, 2017
Dynamic interactions between ecological conditions and the phenotypic composition of populations likely play an important role in evolution, but the direction and strength of these feedbacks remain difficult to characterize. We investigated these dynamics across two generations of threespine sticklebacks from two evolutionary lineages undergoing ...

Experimental evidence for hybridization of closely related lineages in Plasmodium relictum

Molecular and Biochemical Parasitology, 2017
Over 50 avian Plasmodium species have been described. However, PCR-based information shows much broader diversity of genetic lineages in these parasites. This discrepancy indicates insufficient knowledge about taxonomic diversity and boundaries of a single species in avian Plasmodium species.

Hybrid swarm between divergent lineages of mule deer (Odocoileus hemionus)

Molecular Ecology, 2011
AbstractStudies of hybrid zones have revealed an array of evolutionary outcomes, yet the underlying structure is typically characterized as one of three types: a hybrid zone, a hybrid swarm or a hybrid taxon. Our primary objective was to determine which of these three structures best characterizes a zone of hybridization between two divergent lineages ...

Regulation of lineage restricted haemopoietic transcription factors in cell hybrids.

Oncogene, 1995
SCL, GATA-1, GATA-2 and GATA-3 encode lineage restricted haemopoietic transcription factors. We have previously shown that SCL, GATA-1 and GATA-2 are expressed in multipotent progenitors prior to lineage commitment, but are down-regulated during granulocyte/monocyte differentiation.
