Question

The ABO blood group is transmitted in humans as follows: The A and B alleles are dominant to the O allele but codominant with each other. The O phenotype (OO genotype) is known as the "universal donor" in smallvolume blood transfusions, whereas the AB phenotype (AB genotype) can be considered a "universal recipient". A certain human population is at Hardy-Weinberg equilibrium with respect to blood type, with allele frequencies A = 0.5, B = 0.2, O = 0.3. In this population(fill in the blanks), universal donors occur at a frequency of _______, whereas universal recipients occur at a frequency of _______.A. 0.25; 0.30B. 0.09; 0.20C. 0.3; 0.7D. 0.06; 0.04E. 0.15; 0.10

Answer 1

Answer: Option C - 0.3; 0.7

Step-by-step explanation:

Universal donors (O) occur at a frequency of 0.3, whereas universal recipients (AB) occur at a frequency of 0.7

From the information provided in the question, the allele frequency of the O-genotype is 0.3.

However, to get the allele frequency of AB, add up the frequency of each codominant alleles

i.e 0.5 + 0.2 = 0.7, thus AB-genotype is 0.7
