Data from Genome-wide scan for selection signatures in Mexican Sardo Negro Zebu cattle

The sampled Sardo Negro animals included 40 males and 518 females born between 2013 and 2019 in six farms in Mexico's tropical areas. Tail hair samples were collected from each bovine and submitted for genotyping with a 65k SNP chip (Axiom Bovine Genotyping v3 Array). Quality controls on animals and markers of the set were performed using the PLINK software version 1.90 (Purcell et al., 2007) according to the following parameters: minimum SNP call rate of 90%, minor allele frequencies > 0.01, only autosomal SNPs were considered, and only individuals with high genotyping (at least 90% complete call rate) were included.本研究纳入的萨尔德内格罗牛（Sardo Negro）样本共包含40头公畜与518头母畜，均于2013至2019年间出生于墨西哥热带地区的6个养殖场。研究人员采集每头受试牛的尾毛样本，送检采用65k单核苷酸多态性（Single Nucleotide Polymorphism，SNP）芯片（Axiom Bovine Genotyping v3 Array）进行基因分型。随后使用PLINK软件v1.90版本（Purcell等，2007），按照以下参数对受试个体及遗传标记开展质量控制：SNP最低分型检出率不低于90%、次要等位基因频率大于0.01、仅纳入常染色体SNP，且仅保留基因分型完整率不低于90%的受试个体。
