Answer:

A) 1:2:1

Explanation:

Incomplete dominance is an effect observed in the organisms in which the neither of the two alleles controlling a trait is dominant or recessive instead produces a phenotype formed by the mixture of the effect of the two alleles.  Therefore in incomplete dominance, a new trait is produced which is formed by both the alleles.

In the given question, if incomplete dominance is observed in a monohybrid cross which results in two homozygous genotypes and two heterozygous genotypes. In F2 the phenotypic generation produced will be 1:2:1 as the heterozygous genotype will form a new phenotype.
