Blood type codominance practice problems answer key provides solutions to practice problems related to codominance, a mode of inheritance in which both alleles of a gene are fully expressed in the phenotype of a heterozygous individual. Understanding blood type codominance is essential in genetics and has practical applications in blood transfusions and organ transplantation.
Codominance differs from complete dominance, where one allele masks the expression of the other, and incomplete dominance, where the heterozygous phenotype is intermediate between the homozygous phenotypes. In codominance, both alleles contribute to the phenotype, often resulting in a distinct and easily identifiable trait. For example, in the ABO blood typing system, the A and B alleles are codominant, leading to four blood types: A, B, AB, and O. Individuals with type AB blood have both A and B antigens on their red blood cells, while individuals with type O blood have neither A nor B antigens.
