Genomic DNA was extracted using the QIAxtractor and QIAcube robots (Qiagen) following the manufacturer's instructions. Samples were screened at 30 microsatellite markers from Peyran et al. (2020 (link)) and González‐Wangüemert et al. (2014 (link)) following the same genotyping procedure as described in Peyran, Boissin, et al. (2021 (link)). Allele sizes were scored and checked manually using GeneMapper v.5 software (Applied Biosystems). Samples presenting ambiguous peak profiles were re‐amplified, genotyped, and re‐scored, and all peaks that remained unclear were considered as missing data.
