Phylogenetic Analysis of Indian Dromedary Breeds Based on the Mitochondrial D-Loop Marker.

ABSTRACT: The mitochondrial displacement loop (D-loop) region is a non-coding control region that plays a crucial role in replication and transcription, serving as an informative marker for evolutionary and demographic studies. In this study, the complete mitochondrial D-loop sequences from NCBI public database were analyzed across nine Indian and other dromedary populations. Evolutionary and pairwise sequence analysis indicate distinct separation from foreign populations and substantive clustering of Indian breeds within a monophyletic clade. Indian breeds showed greater than 99.4% sequence identity, minimal diversity (π ≈ 0.003), and limited divergence (k = 3-4), whereas Arabian and Iranian populations exhibited more prominent variability (π ≈ 0.004-0.0044; k ≈ 5).
