VNTRs and SNPs

Variable number tandem repeats (VNTRs) contain a variable number of repeat-sequence blocks. (a) A chromosome pair in which one homolog has 6 repeats and the other has 10 repeats. (b) VNTRs are inherited in a  codominant manner.(c) Single nucleotide polymorphisms (SNPs) are single base-pair sequence variants, also inherited in a codominant mannerVariable number tandem repeats (VNTRs) contain a variable number of repeat-sequence blocks.
