Question

Plant A has $2n=12$ chromosomes while plant B has $2n=16$ chromosome. An allotetraploid is raised from them. What is its chromosome number?

• A. $7$
• B. $14$
• C. $28$
• D. $32$

Answer 1

The correct option is C $28$

An allotetraploid is a hybrid that has a chromosome set 4 times that of a haploid organism. Allotetraploids are created as a result of both chromosome sets of each parents being present in gametes. (In this case A+B=28).

So, the correct answer is '28'.
