Question

What is the key to recognising codominance?

Answer 1

Codominance :

1. Codominance is the expression of two alleles ( two different versions of the same gene ) to an equal extent in an individual.
2. It can recognised by the phenotype of the heterozygote, which expresses the phenotype corresponding to both the alleles of the gene.
3. For example: A dog containing fur of both the colours, present in the mother and father of the dog.
4. AB blood group contains allele for blood group A and allele for blood group B.
