Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of aneuploidy types.
Step 2: Detailed Explanation:
A chromosome complement of 2n-2 is nullisomy.
It means a diploid organism is missing both copies of a chromosome pair.
Monosomy (A): 2n-1 (missing one chromosome).
Trisomy (B): 2n+1 (extra chromosome).
Double nullisomy (D): 2n-2-2 (missing two chromosome pairs).
Thus, 2n-2 is nullisomy.
Step 3: Final Answer:
Thus, 2n-2 is nullisomy, which corresponds to option (C).

- Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A): The disruption of $\beta$-oxidation of fatty acids in plants can potentially reduce stress-induced ROS accumulation and improve its stress tolerance.
Reason (R): In plants, $\beta$-oxidation of fatty acids takes place predominantly in peroxisomes, where first enzyme of $\beta$-oxidation viz. fatty acyl CoA oxidase produces large amounts of hydrogen peroxide.
In light of the above statements, choose the correct answer from the options given below. - The serum level of which of the following metabolites can effectively distinguish "Vitamin B12 deficiency" from "Folate deficiency" ?
