It is believed that blood groups A and B were absent from the
aboriginal populations of North and South America. In South America
and the southern part of North America the gene for A is found at
a frequency of 0.05 of less while the gene for B is 0.05 or less
throughout North and South America except for the coastal areas
of Australia. By contrast, the frequency of the O allele in South
America and the southern part of North America is between 0.95 and
1.0. There is an interesting pocket in Central West United States
in which the frequency of A reaches 0.05-0.15 and I believe it may
be attributed to a later movement from siberia.
