Solution
The correct option is D Dd
Heterozygous condition means presence of two different alleles. In case of AA and bb, both the alleles are either dominant or recessive, so they are homozygous. In case of cC, one of the gene is recessive and the other one is dominant; but the representation is not correct as the dominant trait must be written first. Thus, the correct option is Dd in which both recessive and dominant traits are present and represented correctly.
