Method to select breeding animals, isolated and/or recombinant nucleic acid, animal, sperm, embryo and use thereof

摘要

The present invention relates to a method for selecting a domestic animal having desired genotypic properties comprising testing the animal for the presence of a parentally imprinted quantitative trait locus (QTL). The invention further relates to the use of an isolated and/or recombinant nucleic acid comprising a QTL or functional fragment derived therefrom to select a breeding animal or animal destined for slaughter having desired genotypic or potential phenotypic properties. In particular, the properties are related to muscle mass, fat deposition, sow prolificacy, and/or sow longevity.
