As per Mendel's law, describe the independent assortment of two separate traits (round and green seeds) with (wrinkled and yellow seeds) along with diagram.

Text Solution

Verified by Experts

According to law of independent assortment the two or more different traits are independently passed to the next generation. In other words the receiving of different tratis by the off-spring generation is independent of characters (traits) present the parent generation.
This can be proved by taking example of a dihydrid cross. The two pure pea plants have round/green seeds and wrinkled/yellow seeds. In `F_(2)` generation we have round/yellow seeds, round/green seeds, wrinkled/green seeds and wrinkled/yellow seeds. This proves that the characters are passed independently. The diagram is as shown below
