The genome of Triticale is designated as
Show Hint
- Hybrid of wheat (Triticum) × rye (Secale).
- Genome: AABBRR.
- Allohexaploid (2n = 42).
- Combines yield of wheat and stress tolerance of rye.
- AABB
- AABBCC
- AABBDD
- AABBRR
The Correct Option is D
Solution and Explanation
This question tests knowledge of the genomic composition of Triticale, a man-made crop.
Step 2: Detailed Explanation:
Triticale is a hybrid between wheat (Triticum) and rye (Secale).
The genome designation of Triticale is AABBRR (D).
- AABB: Represents the wheat genome (Triticum).
- RR: Represents the rye genome (Secale).
Triticale is an allohexaploid (2n = 42) with genomes from both parents.
Other options:
- AABB (A): Wheat (Triticum).
- AABBCC (B): Hexaploid wheat (Triticum aestivum).
- AABBDD (C): Not a standard designation.
Thus, the genome of Triticale is AABBRR.
Step 3: Final Answer:
Thus, the genome of Triticale is designated as AABBRR, which corresponds to option (D).
