Solution
The correct option is D Incomplete dominance
In a monohybrid cross, starting with parents, which homozygous dominant and homozygous recessive, F1 would be heterozygous for the trait and would express the dominant allele. But in the case of incomplete dominance, a monohybrid cross shows the result as in the above figure. Here, the genotypic and phenotypic ratios are the same. So, we can conclude that when genotypic and phenotypic ratios are the same, the alleles show incomplete dominance. Thus, the correct answer is option D.
