Question

define mendal's law of independent assortment with example

Answer 1

Mendel performed dihybrid crosses in plants that were true-breeding for two traits. For example, a plant that had round seeds and yellow seed color was cross-pollinated with a plant that had wrinkled seeds and green seed color.

In this cross, the traits for round seed shape (RR) and yellow seed color (YY) are dominant. Wrinkled seed shape (rr) and green seed color (yy) are recessive.

The resulting offspring (or F1 generation) were all heterozygous for round seed shape and yellow seeds (RrYy). This means that the dominant traits of round seed shape and yellow color completely masked the recessive traits in the F1 generation.
