Explanation:

Gregor Mendel's experiments with pea plants led to the discovery of the principle of dominance. In his work, he observed that some traits (dominant) masked the expression of others (recessive). Martha Chase was involved in experiments related to DNA as the genetic material. Oswald Avery also worked on DNA's role. Frederick Griffith's experiments were about bacterial transformation.

A. Gregor Mendel
