Data from: The genomic landscape at a late stage of stickleback speciation: high genomic divergence interspersed by small localized regions of introgression

Mark Ravinet, Kohta Yoshida, Shuji Shigenobu, Atsushi Toyoda, Asao Fujiyama & Jun Kitano
Speciation is a continuous process and analysis of species pairs at different stages of divergence provides insight into how it unfolds. Previous genomic studies on young species pairs have revealed peaks of divergence and heterogeneous genomic differentiation. Yet less known is how localised peaks of differentiation progress to genome-wide divergence during the later stages of speciation in the presence of persistent gene flow. Spanning the speciation continuum, stickleback species pairs are ideal for investigating how...

Data from: Functional divergence of a heterochromatin-binding protein during stickleback speciation

Kohta Yoshida, Asano Ishikawa, Atsushi Toyoda, Shuji Shigenobu, Asao Fujiyama & Jun Kitano
Intragenomic conflict, the conflict of interest between different genomic regions within an individual, is proposed as a mechanism driving both the rapid evolution of heterochromatin-related proteins and the establishment of intrinsic genomic incompatibility between species. Although molecular studies of laboratory model organisms have demonstrated the link between heterochromatin evolution and hybrid abnormalities, we know little about their link in natural systems. Previously, we showed that F1 hybrids between the Japan Sea stickleback and the Pacific...
