Welcome to SheepVar!

SheepVar is a public repository of sheep genomic variation that integrates SNPs and InDels with comprehensive annotations, including genomic context, evolutionary conservation, ancestral state, population allele frequencies, molecular QTLs, epigenomic features, selection signatures, and haplotype blocks. In addition, SheepVar provides online genotype imputation services for SNP array data.
