Question

Match the following:

• A. A-IV, B-III, C-I, D-II
• B. A-IV, B-II, C-I, D-III
• C. A-IV, B-III, C-II, D-I
• D. A-I, B-II, C-III, D-IV

Hint:

Sutton and Boveri are credited with developing the chromosomal theory of inheritance, while Sturtevant pioneered the concept of gene mapping.

Answer 1

The Correct Option is C

Here’s the correct matching of concepts with their corresponding scientists:
- A) Behaviour of chromosomes was parallel to the behaviour of genes: This idea is associated with Sutton & Boveri (IV). They proposed the chromosomal theory of inheritance, suggesting that genes are located on chromosomes and follow the same principles of inheritance as chromosomes.
- B) Rediscovery of Mendel’s experiments: This is associated with Correns (III), who, along with other scientists, rediscovered Mendel’s laws of inheritance in the early 20th century.
- C) Distance between genes on chromosome: This concept is associated with Alfred Sturtevant (II), who used gene mapping techniques and showed that the relative distances between genes on chromosomes could be measured.
- D) Mutations: This is associated with Hugo de Vries (I), who is famous for his work on mutations and the theory of mutation as a cause of evolution. Thus, the correct matching is:
- A) Sutton & Boveri → Behaviour of chromosomes was parallel to the behaviour of genes.
- B) Correns → Rediscovery of Mendel’s experiments.
- C) Alfred Sturtevant → Distance between genes on chromosome.
- D) Hugo de Vries → Mutations.
