Molecular Markers in Livestock Improvement

Sanjay Kumar

Abstract


Recent advancements in DNA technologies have made it conceivable to reveal an extensive number of genetic polymorphisms at the DNA sequence level, and to utilize them as markers for assessment of the genetic basis for the watched phenotypic variability. The markers revealing varieties at DNA level are alluded to as the molecular markers.

Based on techniques utilized for location, these markers are arranged into two noteworthy classifications:

• Hybridization-based markers
• PCR-based marker

The molecular markers have interesting genetic properties and methodological advantages that make them more helpful and manageable for genetic examination contrasted with other genetic markers. The conceivable uses of molecular markers in domesticated animals change have been surveyed with reference to routine and transgenic reproducing procedures.

In breeding strategies, molecular markers have a several short-range or immediate applications (viz. parentage determination, genetic distance estimation, determination of twin zygosity and free martinism, and sexing of pre-implantation embryos and identification of disease carrier) and long-range applications (viz. gene mapping, and marker-assisted selection) and long-go applications (viz. quality mapping, and marker-helped choice)
