Existence
of genetic variation indeed forms, the basis for the genetic
improvement of livestock. Single nucleotide polymorphisms
(SNP) represents a potential tool for analyzing the variation
in DNA sequence. SNPs are digital markers and are superior
to any other conventional molecular markers. SNPs have gained
more popularity in several breed improvement programmes,
due to their occurrence in abundance in the genome and the
amenability for automation. In the past one decade, SNPs
have revolutionized the field of molecular biology and thus,
one can hope that genetic maps based on SNPs will assist
animal geneticists and breeders in marker assisted breed
improvement programmes. The present review analyses these
different aspects of SNP as a modern tool, to study genomic
variations for the genetic improvement of dairy animals.
