Question:
What is the somatic chromosome number of Elephant foot yam?
What is the somatic chromosome number of Elephant foot yam?
Show Hint
Some wild triploid forms exist with \( 2n = 3x = 39 \), but the standard diploid cultivated types are \( 2n = 26 \).
Updated On: Jul 10, 2026
- 2n = 2x = 26
- 2n = 2x = 36
- 2n = 4x = 26
- 2n = 4x = 36
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Somatic chromosome number refers to the total number of chromosomes present in the diploid vegetative cells (\( 2n \)) of a plant species.
Step 2: Detailed Explanation:
Elephant foot yam (Amorphophallus paeoniifolius) is an important tropical tuber crop.
The basic chromosome number of the genus Amorphophallus is \( x = 13 \).
The standard cultivated somatic diploid chromosome number of Elephant foot yam is:
\[ 2n = 2x = 26 \]
Step 3: Final Answer:
Hence, the somatic chromosome number of Elephant foot yam is \( 2n = 2x = 26 \).
