With advancement of science the breed identification techniques has moved from phenotype to molecular level identification using blue print of life i.e. DNA. DNA marker based identification of breed is always preferred as it’s highly accurate. Such method becomes absolutely indispensable when phenotype data/information is not at all available like ova, semen, embryo, biological tissue/carcass.
Breed identification especially in admixture or non-descript population has been further challenging task in germplasm management and improvement.

Classical approach of DNA marker based breed identification methods viz. frequency, Bayesian and genetic distance methods needs more number of loci thus increasing cost of breed testing disadvantageously Besides this especially when relative genetic differentiation of populations/breeds in question/investigation, are lower than the compromised accuracy makes such techniques highly ineffective in resolving the enigma of breed prediction. Thus to reduce the cost by decreasing number of loci to be genotyped, without compromising the magnitude of accuracy is imperative and highly desirable. |
