🔹 Codominance – Meaning & Definition
📖 Definition:
Codominance is a form of genetic inheritance in which both alleles in a gene pair are fully expressed in a heterozygous individual. Neither allele is recessive or masked by the other.
🧬 Meaning in Simple Terms:
In codominance, both traits appear equally in the offspring. Instead of blending (as in incomplete dominance), the traits show up side by side.
📌 Key Point:
A form of dominance in which both alleles contribute equally and visibly to the organism’s phenotype.
🧪 Famous Example:
Human Blood Group AB
- The A allele and B allele are codominant.
- If a person inherits an A allele from one parent and a B allele from the other, the blood type is AB — both A and B antigens are expressed.
📋 Summary Table:
| Term | Codominance |
|---|---|
| Alleles type | Both dominant |
| Expression | Both alleles are fully expressed |
| Example | Blood group AB |
| Comparison | Different from Incomplete Dominance (which blends traits) |
