What is Mendel’s Law of Independent Assortment?

A. If the recessive allele is passed for one trait, then it is more likely that the recessive allele will be passed for the other trait.

B. The passing of allele of one trait does not affect the passing of allele of another trait.

C. If the dominant allele is passed for one trait, then it is more likely that the dominant allele will be passed for the other trait.

D. If the dominant allele is passed for one trait, then it is more likely that the recessive allele will be passed for the other trait.
