Explaation; 
-Carbon is the only element that can form so many different compounds because each carbon atom can form four chemical bonds to other atoms, and because the carbon atom is just the right, small size to fit in comfortably as parts of very large molecules. 
-Carbon chains can bond with carbon rings to form very large, complex molecules. These large molecules can be made of many small molecules that are bonded together.
 
        
                    
             
        
        
        
Answer:
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.
