Answer:
Law of independent assortment
Step-by-step explanation:
The law of independent assortment was given by Gregor Mendel which says that one pair of gene get assorted independent of the other pairs of gene during the time of gametogenesis that means each pair of different character(traits) have no association with other characters.
So this independent assortment gives rise to new character combinations in the offspring. For example, the seed color is one trait and seed shape is another trait so during the time of gamete formation these two traits will assort independently. Therefore the right answer is the law of independent assortment.
