The NDDB Biotechnology Laboratory's Animal Genetics wing undertakes research in the disciplines of  cytogenetics and molecular genetics.  This research is directed towards selection of genetically superior dairy animals for breeding programmes being implemented in various milksheds of the country.
 

Karyotyping technology is being used to screen animals for the chromosomal aberrations often associated with sub-fertility and infertility in dairy animals.

The Laboratory provides karyotyping services on payment basis to the cooperative milk producers' unions and state animal husbandry departments. During the last ten years, about  1,625 bulls and bull calves have been karyotyped by the Laboratory.
 

Research in Molecular Genetics focuses on Molecular Characterisation of cattle and buffaloes to identify animals with economically important milk production traits.  The Laboratory is involved in DNA fingerprinting for parentage verification as well as screening of animals for Genetic Diseases like Bovine Leukocyte Adhesion Deficiency Syndrome, Citrullinaemia and Deficiency of Uridine Monophosphate Synthase. 

A research project on "Molecular Characterisation and Preservation of Endangered /Rare Breeds of Cattle and Buffalo of Indian Origin in the form of Frozen Embryos" is currently being undertaken by the Laboratory.  Endangered indigenous cattle breeds such as Vechur, Sahiwal, Red Sindhi, Krishna Valley as well as the Pandharpuri, Toda and Jaffarabadi buffalo breeds have been earmarked for preservation as frozen embryos.
