Select the incorrect statement(s).
I. Multiple alleles are the product of repeated mutations of the same gene, but in different directions.
II. In codominance, both the alleles of the gene express themselves independently as both are dominant.
III. Incomplete dominance results in two different phenotypes in the hybrid.

The correct option is D Statement iii only
Incomplete dominance does not result in two different phenotypes, rather an intermediate phenotype is seen in the hybrid. For example, in Antirrhinum, the cross between red and white-flowered plants, produces pink-flowered plants.
Multiple alleles means a multiple variation of a gene, these alleles are produced due to repeated mutations of the same gene in random directions in the population. Example - 4 alleles for coat colour in rabbits etc.
In codominance, both the alleles of the gene are dominant and are expressed independently. For example, the cross between short-horned cattle of red and white coat colour produces roan coat (patches of red and white) cattle.
