Question

Quizplus · Accepted Answer

A diploid organism contains two of each type of chromosome, one inherited from each parent. This results in a total of 46 chromosomes in human diploid cells (23 pairs). Choice A is incorrect because a diploid organism does not contain several copies of the same chromosome, as that would make it polyploid. Choice B is incorrect because a diploid organism contains both autosomes and sex chromosomes. Choice C is incorrect because a diploid organism contains two copies of each chromosome. Choice D is incorrect because diploid organisms have chromosomes that vary in size.
