C

D
42 and 21

Solution

The correct option is C 21 and 7
Wheat, Triticum, has basic chromosome number, n = 7; thus the hexaploid species (Triticum aestivum) have 6n = 42. Haploid chromosome number is the one present in gametes of that organism; gametes contain half the chromosomes of the somatic cells. Thus, haploid chromosome number of hexaploid wheat is 21. Monoploidy is presence of single basic chromosome set; thus monoploid of hexaploid wheat has x = 7 chromosomes. Correct answer is C.
