The frequency of occurrence of blood groups of the AB0 system in different parts of our planet is different. In some populations, only 2 alleles out of three are found. For example, the American Indians of the Uta, Navajo, and Aboriginal peoples of Western Australia do not have persons with blood types B (III) and AB (1V), but blood types 0 (1) and A (II) are widespread. Bushmen have 0 (1) and B (III) blood groups. The frequency of occurrence of persons with blood group 0 (1) in the surveyed populations: Uta – 97.4%, Australian Aborigines – 48.1%, Navajo – 77.7%, Bushmen – 83%. Determine the genetic makeup of each population.
Genetic structure: populations of Australian aborigines – 0.0961 (AA) + 0.4278 (AO) + 0’4761 (00); the population of the Uta Indians – 0.0001 (AA) + 0.0198 (AO) + 0’9801 (00); the population of the Navajo Indians – 0.0144 (AA) + 0.2112 (AO) + 0.7744 (00); Bushmen population – 0.0081 (BB) + 0.1638 (BO) + 0’8281 (00).
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
