Abstract
Although physiological polytypism is affected by a variety of genetic and environmental and cultural factors, there were few studies of examine relationship between physiological polytypism and gene polymorphism in physiological anthropology. To clear a part of the effects of genetic background to physiological polytypism, we focused the importance of mitochondria and mitochondrial genome. Since mitochondria are considered to have played an important role in cold adaptation, we examined relationship between physiological response and mitochondrial haplogroup during cold exposure. In results, mitochondrial haplogroup affected some physiological parameter (oxygen intake, rectal temperature, etc.). These results suggested that physiological polytypism affected by genetic background.
