Title: What roles does blood types in our ethnic groups based on disease? Post by: flow88 on May 3, 2016 Summarize some of the commonalities of blood types comparing similar ethnic groups. How can this information be used to advance solutions to specific blood-related diseases? (Include your source)

From Wikipedia: Before the discovery of DNA, scientists used blood proteins (the human blood group systems) to study human genetic variation. Research by Ludwik and Hanka Herschfeld during World War I found that the incidence of blood groups A and B differed by region; for example, among Europeans 15 percent were group B and 40 percent group A. Eastern Europeans and Russians had a higher incidence of group B; people from India had the greatest incidence. The Herschfelds concluded that humans comprised two "biochemical races", originating separately. It was hypothesized that these two races later mixed, resulting in the patterns of groups A and B. This was one of the first theories of racial differences to include the idea that human variation did not correlate with genetic variation. It was expected that groups with similar proportions of blood groups would be more closely related, but instead it was often found that groups separated by great distances (such as those from Madagascar and Russia), had similar incidences. Researchers currently use genetic testing, which may involve hundreds (or thousands) of genetic markers or the entire genome.
