Mutation accumulation and fitness effects in hybridogenetic populations: a comparison to sexual and asexual systems.

BMC evolutionary biology - 21 May 2007

Som Christian, Bagheri Homayoun C, Reyer Heinz-Ulrich

Abstract excerpt

BACKGROUND: Female only unisexual vertebrates that reproduce by hybridogenesis show an unusual genetic composition. They are of hybrid origin but show no recombination between the genomes of their parental species. Instead, the paternal genome is discarded from the germline prior to meiosis, and gametes (eggs only) contain solely unrecombined maternal genomes. Hence hybridogens only transmit maternally inherited...
