Project description:We collected whole genome testis expression data from hybrid zone mice. We integrated GWAS mapping of testis expression traits and low testis weight to gain insight into the genetic basis of hybrid male sterility. Gene expression was measured in whole testis from males aged 62-86 days. Samples include 190 first generation lab-bred male offspring of wild-caught mice from the Mus musculus musculus - M. m. domesticus hybrid zone.

Project description:Total genomic DNAs of J118, CdUM4b, the pseudotetraploid hybrid strain HBT1 and the progeny hybrid strain HBP1 were isolated. In an attempt to determine the number of copies of individual chromosomes, we used comparative genome hybridization (CGH) analysis using specially designed whole genome microarrays representing C. albicans and C. dubliniensis genomes. The arrays contained 60 mer probes that fell in three categories either C. albicans specific or C. dubliniensis specific or common to both. The specific probes were expected to work as internal controls when hybridized to parental genomic DNA alone. The arrays were individually hybridized to Cy3-labeled genomic DNA from either of C. albicans (J118), C. dubliniensis (CdUM4b) parents or the somatic psudotetraploid hybrid strain, HBT1 and the pseudodiploid progeny hybrid HBP1. After experimentally determining species-specific probes and common probes, the ratios of intensity on the HBT1 hybrid array to those of either of the parents were calculated. The copy number was determined for the entire chromosomes by comparing individual probe intensities from the pseudotetraploid to either diploid parent genome DNA intensities.
