The enzyme that destroys vitamin B-1 is _______? (IFFCO 2022)

✅Explanation:
Wilhelm Johannsen, a Danish botanist, plant physiologist, and geneticist, coined the term "gene" in 1909. He introduced this term to replace older terms like "pangene" and "determiner," which were associated with now-disproven theories of heredity.

📌 Other Options Explanations:
-Bateson: Coined the term "genetics."
-H. Morgan: Famous for his work with fruit flies (Drosophila) and his contributions to understanding chromosomes and sex-linked inheritance.
-Mendel: Considered the "father of genetics" for his pioneering experiments on pea plants.

🔑Key Points:
Wilhelm Johannsen, the Danish botanist, postulated the word "gene" ("gen" in Danish and German) in 1909 to describe these fundamental physical and functional units of heredity. William Bateson in 1905 coined the term genetics from the word gene.
