Allelic biases in sperm from males that were non-hybrid or hybrid within a lineage versus from males that were hybrids across lineages.

Entries in the table are the ratios of peak heights for the two alleles segregating at the locus in DNA from sperm, standardized against the ratio of peak heights from zygotic DNA (fin clips from the same males). Larger numbers signify greater deviations from 1∶1 segregation in the sperm DNA. The TRD index was calculated from the observed allelic distributions in the PSF2 cross and is the ratio of the frequency of the more common allele divided by that of the less common allele. Not all loci were informative (heterozygous) in each male.?Non-hybrid fish, one each from the surface population, and the Yerbaniz, Tinaja and Pachón cave populations. Abbreviations: Pach = Pachón cave, Yerb = Yerbaniz cave, Tina = Tinaja cave, Moli = Molino cave, Micos = Micos cave, Epi = epigean surface population. *p2 progeny within the old lineage. Asty188, Asty41, and Asty39 are hybrid F2 pedigrees across lineages.
