In a Mendelian monohybrid cross, the `F_(2)`-generation shows identcal genotypic and phenotypic ratios. What does it tell us about the nature of alleles involved? Justify your answer.

Text Solution

Verified by Experts

In case of incomplete dominance monohybrid cross shows `F_(1)` pink flowers (Rr) when in snapdragon Red flowered (RR) and white flowered (rr) parents are crossed.
In `F_(2)` generation genotypic and phenotypic ratio are same .For example:

Same phenotypes and genotypes.
