Question:
Given below are two statements:
Statement I: The recombination frequency of genes vary from 50% to 80%.
Statement II: Recombination can occur anywhere along the length of chromosome.
Given below are two statements:
Statement I: The recombination frequency of genes vary from 50% to 80%.
Statement II: Recombination can occur anywhere along the length of chromosome.
Statement I: The recombination frequency of genes vary from 50% to 80%.
Statement II: Recombination can occur anywhere along the length of chromosome.
Show Hint
Recombination frequency is always $\leq$ 50%.

- Both statement I and statement II are correct
- Both statement I and statement II are incorrect
- Statement I is correct but statement II is not correct
- Statement I is not correct but statement II is correct
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Concept
Recombination frequency is a measure of genetic linkage and is used in the creation of genetic linkage maps.
Step 2: Meaning
Recombination occurs during meiosis when homologous chromosomes exchange genetic material.
Step 3: Analysis
Statement I is incorrect because the maximum recombination frequency between any two genes is 50%. A frequency of 50% indicates that the genes are either on different chromosomes or very far apart on the same chromosome, behaving as if they assort independently. Statement II is generally correct, as crossovers can occur at various points along the chromosome, though certain areas ("hotspots") have higher frequencies.
Step 4: Conclusion
Since recombination frequency cannot exceed 50%, Statement I is false while Statement II remains true. Final Answer: (D)
