CHROMOSOMAL BLOCKS AS MARKERS FOR TRAITS

摘要

The present invention provided a method for predicting a phenotype in a bovine animal, the method comprising analysing a nucleic acid sample from said animal for the presence of at least one genetic marker known to reside in an Linkage Disequilibrium (LD) block in any one of bovine chromosomes BTA-I to BTA-29, wherein said LD block is associated with said phenotype. The phenotype may be selected from the group consisting of Australian profit ranking (APR), Australian selection index (ASR), protein yield (PROT), protein percent (PROT%), milk volume (MILK), fat yield (FAT), fat percent (FAT%), breeding value overall type (Overall Type), somatic cell count (SCC), and breeding value cow fertility (Cow Fertility). Also provided is a linkage disequilibrium unit (LDU) map of any one or more of bovine chromosomes BTA-I to BTA-29', wherein said map comprises a plurality of chromosomal regions, and wherein said regions are defined by their co-inheritance across generations substantially as entire linkage disequilibrium (LD) blocks.
