Answer

  1. Chromosomal theory of inheritance

Explanation:

Mendel's work remains unrecognised till many time because of various reasons but in 1902 Sutton and Boveri gave the chromosomal theory of inheritance which was further expanded by Morgan and Bridges that probed that both sperm and ovum contributed equally in heredity to form offspring and nucleus contains chromosome.

Therefore chromosomes carry the hereditary characters.

This theory also proved Mendel's laws.
