Define co-dominance. How it is proved by using Gossypium species?

Explanation

The phenomenon in which two alleles are both expressed in the heterozygous individual is known as condominance. The codominance was demonstrated in plants with the help of electrophoresis or chromatography for protein or flavonoid substance. Example : Gossypium hirusutum and Grosspium sturtianum , their `F_1` hybrid (amphiploid) was tested for seed proteins by electrophoresis. Both the parents have different banding patterns for their seed proteins . In hybrids , additive banding pattern was noticed . Their hybrid shows the presence of both the types of proteins similar to their parents.
