Quizplus · Accepted Answer

The four major classes of chromosomal rearrangements are inversions, duplications, translocations, and deletions, and these options are listed only in Choice A. Choice B includes reciprocal and non-reciprocal translocations, which are both types of translocations and not separate classes of rearrangements. Choice C includes inversions and duplications, but not translocations, which are considered a major class of chromosomal rearrangement. Choice D includes pericentric and paracentric inversions, which are both types of inversions and not separate classes of rearrangements, but not duplications or translocations.
