How does the law of independent assortment help clarify the inheritance pattern for seed colour and shape in pea plants?

The law of independent assortment states that alleles for different traits segregate independently of one another during the formation of gametes. In pea plants, this means that the inheritance of seed color (e.g., yellow vs. green) occurs independently from seed shape (e.g., round vs. wrinkled). As a result, when these traits are crossed, the combinations of seed color and shape can be predicted using a Punnett square, showing that traits are inherited separately and can result in various phenotypic combinations in the offspring. This helps clarify the inheritance patterns by demonstrating how multiple traits can segregate and assort independently during gamete formation.
