Extensive chromosomal repatterning and the evolution of sterility barriers in hybrid sunflower species.

Genetics - 1 Sept 2005

Abstract excerpt

New species may arise via hybridization and without a change in ploidy. This process, termed homoploid hybrid speciation, is theoretically difficult because it requires the development of reproductive barriers in sympatry or parapatry. Theory suggests that isolation may arise through rapid karyotypic evolution and/or ecological divergence of hybrid neospecies. Here, we investigate the role of karyotypic change in...
