Viability of DNA Fingerprints in Beagles

Abstract

DNA fingerprints were prepared from DNA extracted from 32 Beagles, and 6-13 (9.3 ± 1.9) clear bands were detected in all samples. Based on these bands, the frequency of appearance of a band at the same position by chance in any 2 unrelated dogs was calculated as 0.49 ± 0.13. Although the allelic frequency “q” of 0.29 showed a higher value than that of 0.15 in humans, this figure was similar to that 0.27 reported by Jeffreys (1985) in dogs. The number of bands with chance agreement in dogs without blood relation were conformed to a binomial distribution with an appearance frequency of 0.49. According to these findings, the probability of the occurrence by chance of agreement in all bands in unrelated dogs was estimated as 0.49^9.3=1.3 × 10^-3.
