In a Mendelian monohybrid cross the `F_2` generation shows identical genotypic and phenotypic ratios. What does it tell us about the nature of alleles involved? Justify your answer.

Explanation

In a monohybrid cross, starting with parents which homozygous dominant and homozygous recessive, `F_1` would be heterozygous for the trait and would express the dominant allele. But in case of incomplete dominance, a monohybrid cross shows the result as follows.

`Here the genotypic and phenotypic ratios are the same. So, we canconclude that when genotypic and phenotypic ratios are the same, thealleles show incomplete dominance,
