Question

In incomplete dominance__________________

(a) Phenotype of both allele is expressed

(b) Phenotype of only one allele is expressed

(c) Phenotype of neither of the alleles are expressed

(d) Phenotype of both allele is partially expressed

I have been asked this question in final exam.

This interesting question is from Incomplete Dominance and Codominance topic in section Extension and Deviation from Mendelian Genetic Principles of Cytogenetics

Answer 1

The correct choice is (d) Phenotype of both allele is partially expressed

To explain I would say: In case of incomplete dominance the expression of the phenotype of neither of the allele is complete; although one is more expressed than another.
