Answer

  1. Sutton and Boveri

Explanation:

The Boveri-Sutton chromosome theory, is a prominent theory of genetics  which states that chromosomes are the hereditary units. It elucidates the mechanism underlying the laws of Mendelian inheritance by identifying chromosomes with the paired factors required by Mendel's laws. Chromosomes are the coiled structure composed of DNA which is responsible for the inheritance of characters.
