Individual nucleotide changes to the genome cause a polymorphism called

B) variable number tandem repeats.
C) long tandem repeats.
D) single nucleotide polymorphism.

Question

Quizplus · Accepted Answer

Single nucleotide polymorphisms (SNPs) are the most common type of genetic variation in the human genome, occurring approximately once in every 300 nucleotides. They arise from single nucleotide substitutions, insertions, or deletions and can be used as genetic markers to study genetic variation in populations or individuals. A, B, and C are all types of repeats, but they do not necessarily involve nucleotide changes and are not considered polymorphisms in the same sense as SNPs.
