Extended Data Fig. 6: Sex bias in domestic introgression.

We explicitly tested allele sharing of Bos populations with aurochsen (n = 15) relative to Neolithic Anatolian cattle (n = 3) with (D (water buffalo (n = 3), aurochs population; Neolithic Anatolia, test sample) using two pseudohaploid datasets (SNPs called on the autosome and SNPs called on the X chromosome). In domestic samples (n = 21) there is a pattern of increased autosomal contribution relative to the X chromosome, suggesting introgression was male biased. This contrasts with the patterns observed in wild populations, where the minor component is more often female-biased. Error bars depict the standard error of each test multiplied by 3.
