Pohlavní chromozomy v hybridní zóně myši domácí / Sex chromosomes in the house mouse hybrid zone

Understanding the genetic basis of reproductive isolation is the ultimate goal of the study of speciation. Here I present the results of a study of gene flow and its barriers at sex chromosome markers across the central European portion of the hybrid zone between two house mouse subspecies, Mus musculus musculus and M. m. domesticus. We identified strong introgression of Y musculus chromosome into the domesticus area accompanied by a perturbation of the census sex ratio. In addition, we detected stochastic effects that can distort results of hybrid zone studies. Finally, we confirmed a strong effect of sex chromosomes on reproductive isolation and hence their important role in the process of speciation.
