Abstract:  This experiment was conducted in the Genetics, Breeding and Reproductive Biotechnology Laboratory under Goat and Sheep Production Research Division, Bangladesh Livestock Research Institute (BLRI), Saver, Dhaka, Bangladesh. DNA was extracted from 14 goat breeds and the extracted DNA was observed by gel electrophoresis. Eight goat specific primers were synthesized by ASM-800 DNA synthesizer and screened in the study and all these primers were capable of priming polymorphic amplification pattern in both the breeds. Random amplification of polymorphic DNA – Polymerase Chain Reaction (RAPD-PCR) analysis was carried out using DNA samples of 14 black bengal goat and Jamuna pari goat breeds. Only unambiguous, reproducible and scorable polymorphic fragments were taken into consideration for analysis. Data were analyzed by using a computer programe POPGENE (Version 1.31). Highest level of Nei’s[1] gene diversity value (0.4898) was observed in BMS 1494 locus and the mean genetic diversity was obtained 0.3724 among the 14 goat breeds. The highest number of polymorphism obserbed in primer BM1818.The pair-wise genetic distance value ranged from 0.2500 to 1.000. Dendrogram based on Nei’s[1] genetic distance using Unweighted Pair Group Method of Arithmetic Means (UPGMA) indicated segregation of the 14 goat breeds. Within Jamuna pari goat genetic similarity is low as well as black Bengal goat.
