Hypoxia at high altitudes is a selective pressure that favors individuals with high oxygen saturation in their hemoglobin. This is because high hemoglobin oxygen saturation allows for better oxygen delivery to tissues in hypoxic environments, including high-altitude regions. Tibetan women with alleles for high oxygen saturation in their hemoglobin are more likely to have more surviving children due to better fitness in these environments. This has been shown through studies that have found a positive correlation between the frequency of high-oxygen-saturation alleles and altitude in Tibetan populations, as well as studies that have observed higher fertility rates in women with these alleles.
