Question

Quizplus · Accepted Answer

Cultivated wheat is an allohexaploid, meaning it has six sets of chromosomes originating from three distinct species. Since each species contributes a diploid set of 14 chromosomes, the total is 42 chromosomes (3 species x 14 chromosomes x 2 sets = 42 chromosomes).
