Name the polyploid condition that is formed from the addition of an extra set of chromosomes identical to the normal diploid complement of the same species.
A)autotetraploidy,assuming the normal chromosome complement is haploid
B)allotetraploidy,assuming the normal chromosome complement is diploid
C)alloeuploidy,assuming the normal chromosome complement is diploid
D)autotetraploidy,assuming the normal chromosome complement is diploid
E)autooctoploidyploidy,assuming the normal chromosome complement is haploid

Question

Quizplus · Accepted Answer

Autotetraploidy refers to the condition where an organism has four copies of the same set of chromosomes, which is formed from the addition of an extra set of chromosomes identical to the normal diploid complement of the same species. Therefore, choice D is the correct answer. The other options are either not applicable (e.g., autooctoploidy assuming the normal complement is haploid) or refer to different types of polyploidy (e.g., allotetraploidy and alloeuploidy).
