Chromosome 27 locus effects on milk composition phenotypes.

Genetic associations with the ARS-BFGL-NGS-57448 are shown for the mixed ancestry (MA) and Friesian-Jersey crossbreed (FJX) populations. The number of individuals used in each analysis is indicated in the ‘Animal N’ column. Parameter estimates are given with standard errors in units of kilograms for yield traits, litres for milk volume, and g/100 g of fatty acids for milk fatty acids. Parameter adjusted means are indicated in the same units. The percentage of the total phenotypic variance explained by the ARS-BFGL-NGS-57448 SNP for each trait is indicated in the ‘Pheno variance’ column. P-values of genetic association are indicated in the right-most column.
