Question

Differentiate between incomplete dominance and co-dominance. Substantiate your answer with one example of each

Answer 1

Incomplete Dominance	Co-dominance
F1 generation does not resemble either of the parent but show and intermediate trait. Example:  Snapdragon/Antirrhinum sp/dog flower/mirabilis jalapa/ four O’clock plant.	Both dominant alleles express themselves in F1. Example AB blood group in human.

Incomplete dominance - When homozygous dominant and homozygous recessive parents are crossed all members of F1 progeny will show intermediate trait.

Co dominance - When I^A and I^B are present together they both produce their own sugar / antigen
