Allonemobius Socius

The ground crickets, Allonemobius fasciatus and A. socius are sister species and form a mosaic hybrid zone in the eastern United States. In this study, we developed RAPD markers and constructed genetic linkage maps for the two species, as a first step toward mapping quantitative trait loci that control conspecific sperm precedence. The A. fasciatus map consists of 25 markers mapped to 8 linkage groups, spanning 400.1 contiguous centiMorgans (cM). The average distance between two framework markers is 23.5 cM. The A. socius map consists of 20 markers mapped to 6 linkage groups, spanning 400.5 contiguous cM. The average distance between two framework markers is 30.4 cM. A sex chromosome was identified in the A. socius map. These are the first reported genetic linkage maps for Orthoptera.Key words: Allonemobius, allozyme, cricket, hybrid zone, linkage maps, RAPD.

Abstract Reproductive isolation is a fundamental step in speciation. While sex chromosomes have been linked to reproductive isolation in many model systems, including hominids, genetic studies of the contribution of sex chromosome loci to speciation for natural populations are relatively sparse. Natural hybrid zones can help identify genomic regions contributing to reproductive isolation, like hybrid incompatibility loci, since these regions exhibit reduced introgression between parental species. Here, we use a primate hybrid zone (Alouatta palliata × Alouatta pigra) to test for reduced introgression of X-linked SNPs compared to autosomal SNPs. To identify X-linked sequence in A. palliata, we used a sex-biased mapping approach with whole-genome re-sequencing data. We then used genomic cline analysis with reduced-representation sequence data for parental A. palliata and A. pigra individuals and hybrids (n = 88) to identify regions with non-neutral introgression. We identified ~26 Mb of non-repetitive, putatively X-linked genomic sequence in A. palliata, most of which mapped collinearly to the marmoset and human X chromosomes. We found that X-linked SNPs had reduced introgression and an excess of ancestry from A. palliata as compared to autosomal SNPs. One outlier region with reduced introgression overlaps a previously described “desert” of archaic hominin ancestry on the human X chromosome. These results are consistent with a large role for the X chromosome in speciation across animal taxa and further, suggest shared features in the genomic basis of the evolution of reproductive isolation in primates.
