Question

of a childs eight great grandparents, how many contributed to his nuclear dna? 0 1 4 8

Explanation:

Step1: Understand nuclear DNA inheritance

Nuclear DNA is inherited from both parents. Each parent inherits nuclear DNA from their parents (grandparents). And each grandparent inherits from their parents (great - grandparents).

Step2: Trace the contribution

Since nuclear DNA is passed down through generations in a Mendelian fashion (half from mother and half from father at each generation), all of the great - grandparents contribute to the child's nuclear DNA.

Answer:

8
