Question
Biology Question on Principles of Inheritance and Variation
Which of the following discoveries resulted in a Nobel Prize:
A
X-rays induce sex-linked recessive lethal mutations
B
Cytoplasmic inheritance
C
Recombination of linked genes
D
Genetic engineering
Answer
X-rays induce sex-linked recessive lethal mutations
Explanation
Solution
X-rays induce sex-linked recessive lethal mutations: This research, often associated with the work of Hermann J. Muller, did indeed contribute to our understanding of mutations. Muller himself was awarded the Nobel Prize in Physiology or Medicine in 1946 for his work on the effects of X-rays on genes.
So, the correct option is (A): X-rays induce sex-linked recessive lethal mutations
