A model-based method for identifying species hybrids using multilocus genetic data. Pairwise Sequentially Markovian Coalescent SpeciationĪnderson, E.C., Thompson, E.A., 2002.Lady Amherst's Pheasant (Chrysolophus amherstiae),.The two species provide a good research system as an evolutionary model for testing reinforcement selection in speciation. The results of the study support the scenario of speciation between the Golden Pheasant and Lady Amherst's Pheasant with cycles of mixing-isolation-mixing, possibly due to the dynamics of geographical context in the late Pleistocene. The data further support the occurrence of secondary contact between the parapatric populations since around 30 kya with recurrent gene flow to the present, a pattern that may have been induced by the population expansion of the Golden Pheasant in the late Pleistocene. The results provide clear evidence that the gene flow between the two pheasants was consistent with the predictions of the isolation with migration model during divergence, indicating that there was long-term gene flow after the initial divergence (ca.
Using a newly assembled de novo genome of Lady Amherst's Pheasant and resequencing of widely distributed individuals, we reconstructed the demographic history of the two pheasants by the PSMC (pairwise sequentially Markovian coalescent) method. In this study, we estimated the pattern of gene flow during the speciation of the two pheasants using the Approximate Bayesian Computation (ABC) method based on data from multiple genes. amherstiae), both of which exhibit significant plumage dichromatism, are currently parapatric in southwestern China with several hybrid recordings in field. Two species in the genus Chrysolophus, the Golden Pheasant ( C. The mechanism of how speciation in sexually dichromatic species operates in the face of gene flow remains an open question. It is widely accepted that speciation requires an interruption of gene flow to generate strong reproductive isolation between species. Understanding speciation has long been a fundamental goal of evolutionary biology.
