As discussed previously, the ABO locus in humans has three alleles, where IAand IBare co-dominant and i is recessive to each. Su
Ivahew [28]

Answer:

Explanation:

using the formula p² + 2pq + 2pr + q²+ 2qr + r² = 1 where p is IA allele is 0.35 and q is IB allele is 0.15.

Thus, the expected frequency of people with type AB blood in this population will be (2pq) = 2 x 0.35 x 0.15 = 0.105

b. The expected frequency of people with type A blood will be p² + 2pr = where r is found using the formular p + q + r = 1 = 1 - (p+q) = 1 - (0.35+0.15) = 0.5

Thus, we have the expected frequency of people with type A blood to be     (0.35² + 2x0.35x0.5) = 0.4725.

c.    <u> p² + 2pr</u> + <u>2pq </u>+ <u>q² + 2qr</u> +<u> r²</u>

       AA AO      AB      BB BO     OO

         1850       180        635      2335

frequency of IA- p = (1850 + 180/2) / 5000 = 0.388

frequency of IB- q = (635 + 180/2) / 5000 = 0.145

frequency of i- r = 2335/ 5000 = 0.467.

since r² = 2335, r = √2335 = 48.32

using the formula p + q + r = 1
