Take This Quiz Up To Chromosomal Inheritance

In the study of biology, the chromosome theory of inheritance (often referred to as the Sutton-Boveri theory) explains how chromosomes are the carriers of genetic material that we receive from our respective parent cells. What do you know of how chromosomal inheritance works? Let’s find out.
