ABSTRACT: This study was conducted on 45 heads (15 of each breed) of three Sudanese domestic goat breeds (Desert goat, Nubian goat and Taggar goat) to pursue complete mitochondrial DNA analysis using PCR-RFLP method to detect the mitochondrial DNA diversity of two mit-DNA haplogroups, lineage A and lineage D. The results revealed that most individuals of the three breeds belonged to lineage A with frequencies 0.2 of Desert goats, 0.6 of Nubian goats and 0.6 of Tagar goats. Some of the individuals belonged to modified lineage A with frequencies 0.2 of Desert goats, 0.2 of Nubian goats and 0.2 of Tagar goats; no individual of each belonged to lineage D. In conclusion, the appearance of individuals that belonged to modified lineage A in the different goat breeds might be due to mutation resulted from insertion or deletion of events and might a criterion of the Sudanese indigenous goat breeds. However this suggestion needs more confirmative analysis.
