High density genotyping dataset associated to the paper entitled « The genetic history of Mayotte and Madagascar cattle breeds mirrors the complex pattern of human exchanges in Western Indian Ocean » (Magnier et al., 2022)

This dataset consists of genotypes of 528 animals belonging to 13 cattle populations for 680338 variants (SNPs) in plink format. The compressed archive contains two files: (i) a genotyping data file named "cattle_680338variants_528individuals_12.ped" (528 rows, 1360682 columns) that contains, for each individual, six information columns (breed ID, animal ID and four columns with data coded 0 or -9) and the genotypes (alleles 1 and 2) for the 680338 SNPs ; and (ii) a map file named "cattle_680338variants_528individuals_12.map" (680338 rows, 4 columns) that contains for each SNP, the autosome number, the SNP name, a column with data coded 0 and the SNP position on autosome.
