SpletShort Tandem Repeats (STRs) are 2 to 6 base pair DNA sequences that are scattered throughout the genome. These short sequences can be repeated multiple times and the number of these repeats is highly variable between individuals. This high variability allows for the identification of different samples from one another. Splet01. nov. 2024 · Short tandem repeats, consisting of consecutively repeated units of 1–6 base pairs (bp), represent a large source of genetic variation.
