Q. 14. With the help of an example differentiate between incomplete dominance and co-dominance.
Incomplete dominance is a phenomenon where two contrasting alleles are present together but neither of the alleles is dominant over the phenotype performed is intermediate of the two alleles
e.g., the kind of inheritance in the dog flower (Snapdragon orAntirrhinumspecies) in which the intermediate trait is expressed in -generation.
Codominance is a phenomenon in which when two contrasting alleles are present together and both of the alleles express themselves.
e.g., AB blood group in humans where both the alleles are expressed to produce RBC surface antigens A and B.
(i) Coss showing incomplete dominance
(ii) Blood group showing co-dominance
