Genetic markers in the bovine PIT-1 gene are disclosed which are associated with increased milk production and increased protein and fat content in cattle. Further, novel sequence data from intron regions of the gene are disclosed which may be used in a PCR test to screen for the presence of the marker.

Genetic marker for improved milk production traits in cattle

A method of genetically evaluating animals by using mitochondrial DNA is disclosed. Polymorphisms in mitochondrial DNA are detected by isolating, fragmenting, and sequencing the DNA. The restriction patterns and nucleotide sequences of mitochondrial DNA of different animals are correlated to expressed traits in the animals. This may be confirmed by comparing results to expression of the trait in maternal lineages of animals. Further, effects of maternal lineages are determined by partitioning maternal genetic variation from nuclear variation.
