Sample collection and genotyping-by-sequencing data
One hundred quails were sampled for this study; 78 captured wild African harlequin quails and 22 domestic Japanese quails from Siaya and Kajiado Counties of Kenya, respectively. This comprised an equal number of male and female individuals for every visited farm. Wild African harlequin quails were captured around homesteads using traditional methods described by Wamuyu et al. (2017). DNA extracted from blood samples was sequenced using the genotyping-by-sequencing (GBS) approach and the generated sequence data was extracted from our previous publication (Ogada et al., 2021).
