WebApr 11, 2024 · They consist of tandem repeats of short DNA sequences, typically between 1-6 base pairs in length. Microsatellites are highly variable, and the number of repeats can differ between individuals. This variability makes microsatellites useful for identifying genetic differences between individuals and for mapping the location of genes.
