A) One gene locus with three incompletely dominant (co-dominant) alleles.
B) One gene locus with two incompletely dominant (co-dominant) alleles and two recessive alleles.
C) One gene locus with two incompletely dominant (co-dominant) alleles and one recessive allele.
D) Two unlinked gene loci each with two alleles, one dominant and one recessive.
Correct Answer: C

ABO blood groups occur on one gene locus, where \[{{I}^{A}}\] and \[{{I}^{B}}\] are co-dominant, and is the recessive allele. The allele; is expressed only when present in the homozygous condition.You need to login to perform this action.
