Question

Which crop is an example of a hexaploid organism with a 6n = 42 chromosome number?

Options

• Wheat (Triticum)

• Rice

• Banana

• Corn

Answer 1

Wheat (Triticum) is a hexaploid organism with 6n = 42 chromosomes. Polyploid crops like wheat and banana are common in plants, where the increase in chromosome sets results in increased size and vigor. Bananas are examples of triploid (3n) organisms. Polyploidy is generally rare and lethal in mammals.
