Instrument\/Gear  Identification of Description<\/strong><\/td>Flipper tagging consisted of applying an ID-tag (Dalton Jumbo-rototag or Allflex ear tags) to the seal\u2019s hindflipper while the seal was resting on shore. Tissue sampling during tagging was possible by recovering a small skin plug stuck to the tag pliers, or manually using a 2mm sterile biopsy punch (Miltex). Samples were stored in 95% ETOH and then kept frozen at -20deg C until processing.<\/td><\/tr>
Analysis Methodology<\/strong><\/td>DdRADSeq data was obtained from tissue samples.<\/td><\/tr>
Data Processing\/<\/strong> Reduction Methodology<\/strong><\/td>Genome mapping, heterozygosity and inbreeding estimations, relatedness analyses<\/td><\/tr>
Explanations of Data Quality Flags<\/strong><\/td>Samples with low mapping rate were not included in the final analyses.<\/td><\/tr>
