Question

Which of the following discoveries resulted in a Nobel Prize?

• A. Genetic engineering
• B. X-rays induce sex-linked recessive lethal mutations
• C. Cytoplasmic inheritance
• D. Recombination of linked genes

Answer 1

The correct option is B X-rays induce sex-linked recessive lethal mutations

H. J. Muller in 1946 was awarded Nobel Prize for his discovery of the production of mutation by X-ray irradiation.

He was an American geneticist, educator, and Nobel laureate best known for his work on the physiological and genetic effects of radiation, which in the following years led to increased scrutiny to the use of radioactive elements and safety procedures.

Therefore, the correct answer is option B.
