Polyploid with multiple complete genomes derived from two or more different species is
Polyploid with multiple complete genomes derived from two or more different species is
Show Hint
Allopolyploid:
- Genomes from different species.
- Autopolyploid: Genomes from same species.
- Examples: Wheat (allopolyploid), Banana (autopolyploid).
- Genomes from different species.
- Autopolyploid: Genomes from same species.
- Examples: Wheat (allopolyploid), Banana (autopolyploid).

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of polyploidy types.
Step 2: Detailed Explanation:
Allopolyploid is a polyploid with multiple complete genomes derived from two or more different species.
It arises from hybridization between different species followed by chromosome doubling.
Example: Wheat (Triticum aestivum) is an allohexaploid.
Autopolyploid (B): Multiple genome sets from the same species.
Aneuploid (C): Missing or extra individual chromosomes (not complete sets).
Synthetic autopolyploid (D): Artificially induced autopolyploid.
Thus, allopolyploid is the correct answer.
Step 3: Final Answer:
Thus, allopolyploid is the polyploid with multiple complete genomes from different species, which corresponds to option (A).

- 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" ?
