Allele frequency is the relative frequency of a certain alleletype among a certain population. Suppose that within a certainarea, the allele frequency of A, B and O are 0.2, 0.1, and 0.7,respectively. Suppose that when randomly picking up a person, thefirst allele type is independent of the second allele typeregardless of the type. Calculate the following probabilities:
• The probability for this person to have type O blood.
• The probability for this person to have type A blood.
• The probability for this person to have type B blood.
• The probability for this person to have type AB blood.
