Transcriptome-wide signature of hybrid breakdown associated with intrinsic reproductive isolation in lake whitefish species pairs (Coregonus spp. Salmonidae)

ABSTRACT: Genetic analyses of speciation have focused nearly exclusively on retrospective analyses of reproductive isolation between highly divergent species. Yet, a full understanding of the speciation process must encompass analysis of the consequences of genomic divergence in young lineages still capable of exchanging genes under natural conditions. The accumulation of conditionally neutral genetic variation may lead to the evolution of divergent gene networks. In a hybrid background, such mutations may no longer compensate one another, resulting in the appearance of selectively disadvantageous traits, including disruption of gene expression regulation. Here, we documented genome-wide patterns of gene expression divergence between young lineages of normal and dwarf lake whitefish and their backcr
