Distribution of milk and mammary genes across all bovine chromosomes. In this chromosome map, each of the 30 bovine chromosomes is illustrated by a pair of columns, with genomic locations of milk and mammary genes in the first column, and milk-trait QTL in the second column. Note that the milk and mammary genes are distributed across all chromosomes.
