Pit - 1 gene polymorphism and trait selection in animals

摘要

The present invention relates to a genetic marker used to distinguish amongst animals a trait for milk producing capabilities or muscular beef producing capabilities said genetic marker comprising a mutation in a fragment of a Pit-1 gene wherein after digestion with a restriction endonuclease, three allele patterns are observed, the fully digested pattern being indicative of a trait for muscularity in said animal, while the intermediate digested/nondigested pattern or the nondigested pattern being indicative of a milk producing trait in said animal. A process and kit using this genetic marker is also disclosed.
