Question:
Choose the correct statements among the following:
A) Some genes are very tightly linked on the same chromosome, which shows higher recombination.
B) Sutton proposed the chromosome theory of inheritance.
C) Behaviour of the chromosome was parallel to the behaviour of genes.
D) Mendel's selection of one of the contrasting traits is seed shape as inflated and wrinkled.
Choose the correct statements among the following:
A) Some genes are very tightly linked on the same chromosome, which shows higher recombination.
B) Sutton proposed the chromosome theory of inheritance.
C) Behaviour of the chromosome was parallel to the behaviour of genes.
D) Mendel's selection of one of the contrasting traits is seed shape as inflated and wrinkled.
Show Hint
Remember: Linked genes = "stay together" (low recombination); Chromosome behavior = Gene behavior.

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Concept
Principles of inheritance, chromosomal theory, and linkage.
Step 2: Analysis
* Statement A is incorrect: Tightly linked genes show lower, not higher, recombination. * Statement B is correct: Sutton (along with Boveri) proposed the chromosomal theory of inheritance. * Statement C is correct: The chromosomal theory of inheritance is based on the observation that the behavior of chromosomes during meiosis parallels the behavior of genes. * Statement D is incorrect: Mendel's contrasting traits for seed shape were round and wrinkled, not inflated and wrinkled (inflated/constricted refers to pod shape).
Step 3: Conclusion
Statements B and C are correct.
Final Answer: (D)
