Conclusion and Practical Applications. In an individual with the IAIB genotype, both antigens are synthesized and displayed on the cell membrane, demonstrating that neither allele is suppressing the other.
Understanding Codominance Alleles in Genetic Inheritance Patterns
Codominance of alleles represents one of the fundamental patterns of inheritance that deviates from the simple dominant-recessive relationship taught in introductory biology. Distinguishing Codominance from Incomplete Dominance It is crucial to differentiate codominance from incomplete dominance, as both involve the blending or mixing of traits but through different mechanisms.
These examples highlight how codominance contributes to the rich genetic diversity observed within populations, as heterozygotes possess a unique phenotype that is not a compromise but a full expression of both variants. In codominance, however, the phenotypes are not blended; instead, both traits appear distinctly and fully expressed.
Understanding Codominance Alleles in Genetic Inheritance Patterns
Because the heterozygous phenotype is distinct and often fully functional, natural selection can act on multiple phenotypes simultaneously. In human genetics, the MN blood group system is another clear-cut case, where the LM and LN alleles are codominant, resulting in individuals expressing both M and N antigens on their red blood cells.
