B)codominant
C)incompletely dominant
D)sex-linked traits

Question

Quizplus · Accepted Answer

The blood proteins A and B are codominant, which means that they both express themselves fully in the presence of each other. Therefore, individuals who inherit both A and B alleles will have type AB blood, which displays both A and B antigens on the surface of their red blood cells. This is in contrast to incomplete dominance, in which the heterozygous phenotype displays a blend of both alleles, or simple dominant and recessive traits, in which the dominant allele masks the expression of the recessive allele. The ABO blood grouping is also not a sex-linked trait, as it is not located on the sex chromosomes.
