Abstract

This paper describes five genetic markers from the sheep genome. The polymorphic nature of these new markers, called microsatellites, is due to differences in the number of dinucleotide repeats at each locus. The advantages of these markers compared with other DNA markers are the speed and ease with which individuals can be analysed and the highly polymorphic nature of the loci. The five loci described in this paper had between 4 and 19 loci at each locus, with PIC values ranging from 0.41 to 0.90. It is likely that microsatellites will provide the next generation of parentage test for domestic animals as they are cheaper to perform and simpler to analyse than DNA fingerprints.
