: Random amplification of polymorphic DNA-Polymerase Chain Reaction (RAPD-PCR) analysis was carried out using
DNA samples of 30 animals ofRathi cattle and 42 animals of Tharparkar cattle. Genomic DNA was isolated as per standard protocol
and evaluated for its quality, purity and concentration. Twenty three random primers were screened out of which 15 primers yielded
satisfactory amplifications and were used for further analysis. Average numbers ofpolymorphic fragments per primer were 7.07±0.86 in
Rathi and 6.80±0.61 in Tharparkar cattle. The percentage of polymorphic bands in these two cattle breeds were 86 and 87%,
respectively. Within breed genetic similarities for pooled over primers in the animals of Rathi and Tharparkar breeds were 0.577±0.30
and 0.531±0.02, respectively on the basis of band frequency (BF) and 0.645±0.04 and 0.534±0.04, respectively on the basis of band
sharing (BS). Averages of between breed genetic similarities for pooled over primers were 0.97 and 0.92 according to BF and BS,
respectively, which reflect higher degree of genetic similarity between Rathi and Tharparkar cattle breeds. Index of genetic distance
based on BF and BS for pooled over primers was 0.030±0.011 and 0.088±0.031, respectively. Percentage of polymorphic bands and
within-breed genetic similarities on the basis of band frequency (BF) and band sharing (BS) for pooled over primers revealed higher
genetic similarity in Rathi than Tharparkar cattle population. High estimates of between breed genetic similarities for pooled over
primers indicated that either Rathi is having decent from Tharparkar or both the cattle breeds are having common descent. Low value of
Index of genetic distances between these two cattle breeds may be due to the fact that Rathi and Tharparkar cattle breeds are the native
of Thar Desert in Northwest India. The results of between breed genetic distances also confirm the existence of high degree of genetic
similarity between these two breeds of cattle.
