Direction: In the following questions a statement of assertion (A) is...
Explanation:
Assertion (A) and Reason (R) Analysis:
Assertion (A): Number of chromosomes in one genome is equal to number of linkage groups.
Reason (R): Two homologous chromosomes form a linkage group.
Evaluation of Assertion and Reason:
- The number of chromosomes in one genome is indeed equal to the number of linkage groups because each chromosome is associated with a specific linkage group.
- Homologous chromosomes, which are pairs of chromosomes containing the same genes, do form a linkage group. However, this alone does not explain why the number of chromosomes in one genome is equal to the number of linkage groups.
Conclusion:
The assertion (A) is true since each chromosome is associated with a linkage group. The reason (R) is also true as homologous chromosomes form linkage groups. However, the reason does not provide a direct explanation for the assertion. Therefore, the correct choice is option B: Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
