Pedigrees have a long history in classical genetics, agronomics, evolutionary ecology, and ex situ captive breeding. Use of molecular techniques has expanded the variety of species for which pedigrees can be constructed. However, molecular pedigrees almost exclusively consider microsatellite loci, despite advances in high-throughput sequencing allowing development of genomic marker sets in nearly any organism. Here we generate a novel set of genomic SNPs derived from ddRAD sequencing in two populations of Weddell seals (Leptonychotes weddellii) and describe the diversity and differentiation between them. We then compare and contrast parentage assignment rates and accuracy in one population that has been the subject of long-term monitoring. Specifically, we consider pedigrees constructed using two sets of markers (microsatellites and SNPs), two pedigree construction software (CERVUS than Sequoia), as well as varying the groupings of candidate parents (either all individuals simultaneously, only individuals born before a focal year, or only individuals known to have survived to a focal year). ddRAD sequencing returned between 1568 and 3240 loci depending on whether both populations were considered simultaneously or individually. Parentage assignment rates were always higher using CERVUS than Sequoia, with the latter at times either not assigning parentage or creating “inferred parents”. In all cases, “polarizing” the datasets (e.g., including year of birth) significantly improved assignments. This represents one of the first direct comparisons of pedigree construction using different markers in the same set of individuals, and the SNPs described here will be a resource for continued pedigree construction, and future research in Weddell seals.
