Q58

Bread wheat is

A.
Diploid
B.
Haploid
C.
Tetraploid
D.
Auto-allopolyploid
Answer

Answer: Option D

Solution

Answer: Option D
Solution:
Bread wheat is Auto-allopolyploid.
Autoallopolyploid, is having one set of chromosomes (or one genome) in a more than diploid state.
Bread Wheat (Decaploid triticale) (AABBDDRRRR) is an example of auto-allopolyploidy. This plant has two copies of each of the three genomes of bread wheat (ABD) and four copies of that of rye genome (R). Thus the rye genome is in autotetraploid condition.
