Predict how many genetically different offspring could be produced by outcrossing two 2n=4 individuals (just account for independent assortment and not crossing over).

16 genetically different offspring

Explanation:

This is the case as each parent has the ability to produce 4 uniquely different gametes through independent assortment. With such a scenario where each parent can product 4 uniquely different gametes multiplied by 4 parents, you have 16 offspring. So there's the possibility of producing 16 offspring that are unique.
