How did Mendels experiments show that different traits are inherited independently? Explain. (Delhi 2017)

Mendel’s dihybrid cross showed that each trait expressed independently of the other when two pairs of characteristics or characters were taken into account. Mendel was able to develop the Law of Independent Assortment, which deals with the independent transfer of traits.

The given cross could provide a clear explanation for this:

F₂ generation ratio : Round-yellow = 9 : Round- green = 3: Wrinkled-yellow = 3: Wrinkled-green = 1

Phenotypic ratio of F₂ Generation = 9:3:3:1

F₂ generation genotypic ratio: 1:2:2:4:1:2:1:2:1
