Law of Independent Assortment :
(1) The law of independent assortment states that two parents differing from each other in two or more pairs of contrasting characters are crossed, then the inheritance of one pair of characters is independent of that of the other pair of characters.
(2) From the results of the dihybrid cross, it is obvious that the character of yellow colour of the seed is in no way linked with the round shape of the seed. Similarly the green colour of the seed is not linked with the wrinkled shape of the seed. This is due to the fact that in the above cross, the two pairs of characters segregate independently. other words, there is independent assortment of characters during inheritance.
