Mitochondrial DNA of the Arabian Camel Camelus dromedarius.

Simple Summary: Mitochondrial DNA evolves rapidly, is maternally inherited, and is relatively small and compact in most animal species, making it a popular marker in molecular studies. In genomics, the study of mitochondrial DNA is important for understanding the origins, history, and adaptation of domesticated species. This review examines the D-loop region of mitochondrial DNA in Arabian camels to explore maternal inheritance, genetic diversity, and evolutionary history. It highlights significant genetic differences and adaptive traits in the mitogenome of Arabian camels. The D-loop region contains extensive polymorphisms and haplotypes, which provide insights into camel domestication and breeding processes. Comparative analyses with other camelid species reveal unique genetic signatures in the Arabian camel. Finally, this review integrates recent advancements in mitochondrial genomics, demonstrating potential applications in conservation and breeding programs to enhance the understanding and preservation of Camelidae genetics. The Camelidae family, ranging from southwest Asia to north Africa, South America, and Australia, includes key domesticated species adapted to diverse environments. Among these, the Arabian camel (Camelus dromedarius) is vital to the cultural and economic landscape of the Arabian Peninsula. This review explores the mitochondrial DNA of the dromedary camel, focusing on the D-loop region to understand its genetic diversity, maternal inheritance, and evolutionary history. We aim to investigate the unique characteristics of Arabian camel mtDNA, analyze the D-loop for genetic diversity and maternal lineage patterns, and explore the implications of mitochondrial genomic studies for camel domestication and adaptation. Key findings on mtDNA structure and variation highlight significant genetic differences and adaptive traits. The D-loop, essential for mtDNA replication and transcription, reveals extensive polymorphisms and haplotypes, providing insights into dromedary camel domestication and breeding history. Comparative analyses with other camelid species reveal unique genetic signatures in the Arabian camel, reflecting its evolutionary and adaptive pathways. Finally, this review integrates recent advancements in mitochondrial genomics, demonstrating camel genetic diversity and potential applications in conservation and breeding programs. Through comprehensive mitochondrial genome analysis, we aim to enhance the understanding of Camelidae genetics and contribute to the preservation and improvement of these vital animals.
