Distribution of cows for predicted transmitting ability (PTA) for fat yield by allele combination for SNP BFGL-NGS-117985 in the PGLYRP - IGFL1 region of Bos taurus chromosome 18. This SNP explained 13.68% of PTA variation (R2 = 0.1368) of fat yield, was among the top 20 significant SNP effects for fat and protein yields, service-sire and daughter calving ease, service-sire stillbirth, net merit (ranked 1st), milk yield (ranked 9th), and productive life (ranked 16th), and was among the top 100 effects for fat and protein percentages. A) All cows. B) Cows homozygous for major allele of SNP. C) Cows heterozygous for SNP. D) Cows homozygous for minor allele of SNP.
