Short tandem repeats (STRs) are DNA sequences of 1–6 bp that are repeated in tandem from several to hundreds of times. Because they mutate frequently by adding or deleting copies of the repeat, STRs can have many distinct alleles in a population. Given their high mutation rate and polymorphism, STRs have been widely used in population genetic studies. Notably, STR typing has made a great contribution to understanding human evolutionary history. For example, in 2009, Tishkoff et al.

AbstractSkin color is highly variable in Africans, yet little is known about the underlying molecular mechanism. Here we applied massively parallel reporter assays to screen 1,157 candidate variants influencing skin pigmentation in Africans and identified 165 single-nucleotide polymorphisms showing differential regulatory activities between alleles.
