• Genomic inbreeding and selection signatures in the local dairy breed Icelandic Cattle

    3 monthes ago - By Animal Genetics

    Summary
    Icelandic Cattle is the only dairy cattle breed native to Iceland. It currently numbers ca. 26 000 breeding females. We used 50k genotypes of over 8000 Icelandic Cattle to estimate genomic and pedigree‐based inbreeding and to detect selection signatures using the integrated haplotype score. We used 47 Icelandic bulls genotyped with a 770k SNP chip to estimate LD decay for comparison with other Nordic dairy cattle breeds. We detected ROHs on the autosomes and computed ROH‐based autosomal inbreeding coefficients. Average inbreeding coefficients according to pedigree and ROHs were...
