Answer:
Independent assortment
Explanation:
The law of independent assortment says that genes for different traits or characteristics assort independently from each other during gamete formation. So each contrasting character's pair assort independently and do not show any association with the pair of other characters.
So after gamete formation collectively the gametes have all the possible combinations of alleles because all the genes are assorted independently in gametes.
