However, the recent whole-genome and larger mitochondrial DNA analyses revealed that Gobi and Himalayan brown bears are already diverged lineages and have a shared ancestry, the oldest lineage of all other brown bears. A 263 base-pair segment of the mitochondrial DNA was sequenced for 3 bears and a single haplotype was gained.
Nevertheless, the recent comprehensive and extensive mitochondrial DNA studies have shown that Gobi and Himalayan brown bears are already distinct branches and share a common origin, the oldest lineage of all other brown bears. A 263 base-pair segment of the mitochondrial DNA was sequenced for 3 bears and a single haplotype was obtained.
