A) triploid with 21 chromosome
B) hexaploid with 42 chromosome
C) tetraploid with 30 chromosome
D) diploid with 14 chromosome
Correct Answer: B
Solution :
Common cultivated wheat is an example of allopolyploidy. Allopolyploidy is the doubling of chromosome number in \[{{F}_{1}}\] hybrid which is derived from two distinctly different species. Triticum aestivum is hexaploid with \[2n=42\] and derived from three diploid species (i) AA-Triticum aegilopoides \[(2n=14)\] (ii) BB-Aegiiops speltopides \[(2n=14)\] and (iii) W-Aegilops squarrosa \[(2n=14)\] followed by chromosome doubling.
