उत्तर
Mendel’s law of independent assortment, states that in a dihybrid cross, the alleles of one pair segregate independently of the alleles of other pairs at the time of gamete formation and the gametes assort independently at the time of zygote formation. Thus, an inheritance of one; the character does not interfere, the inheritance of other characters.
