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.

This independent assortment of traits leads to some new combination of characteristics in the offspring. Therefore the correct answer is independent assortment.
