Go to this page: https://en.wikipedia.org/wiki/Blood_type_distribution_by_country. It has a list of blood group frequencies by country. China and Iceland have very similar frequencies for type O positive. Propose a realistic hypothesis to explain this similarity. Also, China has a very large population. Assuming that it meets the Hardy-Weinberg assumptions, estimate the frequency of the O type allele. You must be homozygous for the O type allele to have type O blood.
