Abstract

The genetic relation among different populations and breeds of goats in Bangladesh was studied using 15 microsatellite markers. A total of 181 goat samples- 36 from Black Bengal of western part (BBW), 39 from Black Bengal of central part (BBC), 40 from Black Bengal of Hilly region (BBH), 28 from exotic breeds (JAM) and 39 from crossbred (CRW) were genotyped. The allele number per locus ranged from 2 to 12. The average number of alleles per population was 5.69 ± 2.32, 5.38 ± 2.02, 5.23 ± 2.28, 6.08 ± 2.33, and 5.77 ± 2.35 for BBW, BBC, BBH, CRW and JAM, respectively. Heterozygosity was found in the range from 0.5049 ± 0.0222 (BBC) to 0.5751 ± 0.0262 (JAM). The genetic distance (DA) between BBC and JAM was the highest (0.0627) and that between JAM and CRW was the lowest (0.0037). In the phylogenetic dendrogram, BBC and BBH grouped in the same cluster, while CRW and JAM formed another cluster. BBW formed a third cluster between those two clusters. The closest genetic relation between BBW and CRW indicates the introgression of exotic genes occurred more in BBW than BBC and BBH.
