What theory suggests genes are located on chromosomes in exact locations?

The answer is:

The Boveri-Sutton Chromosome Theory also known as inheritance theory

Explanation:

The Boveri-Sutton Chromosome Theory also known as inheritance theory, was discussed and debated during the first years of the twentieth century. It was accepted by some scientists but strongly rejected by others. This theory states that genes are found at specific locations on chromosomes, and that the behavior of chromosomes during meiosis can explain Mendel's laws of inheritance.

Answer: the inheritance theory suggests that genes are located on chromosomes in exact locations.

The chromosome theory of inheritance was made by Boveri and Sutton, and it states that genes are found at certain locations on chromosomes, and during meiosis, the behavior of these chromosomes can expound why genes are inherited, which is consistent with Mendel's laws of inheritance.
