Quizplus · Accepted Answer

Single base differences, also known as single nucleotide polymorphisms (SNPs), are the most frequent cause of DNA polymorphism. This is because they can occur at a much higher frequency than larger structural variations such as duplications, inversions, and translocations, which tend to be more rare events. Ploidy, which refers to changes in the number of whole sets of chromosomes, can also lead to polymorphism but it is not as common as SNPs.
