Question
In humans, the ABO blood group, the A and B alleles produce proteins in the surface of red blood cells while the O allele produces nothing. The following genotypes are possible:OO AO AA BO BB AB
Compared to the B allele the A allele would be: A. dominant B. recessive C. incompletely dominant D. codominant In humans, the ABO blood group, the A and B alleles produce proteins in the surface of red blood cells while the O allele produces nothing. The following genotypes are possible:
OO AO AA BO BB AB
Compared to the B allele the A allele would be: A. dominant B. recessive C. incompletely dominant D. codominant
OO AO AA BO BB AB
Compared to the B allele the A allele would be: A. dominant B. recessive C. incompletely dominant D. codominant
Explanation / Answer
The correct answer is D) codominant.
In ABO blood grouping system, A and B alleles are dominanat over i because AO and BO genotypes show A and B blood groups, respectively. A and B alleles are codominant because AB genotype shows AB blood group. So, option D) codominat is correct.
