Microsatellites, or Simple Sequence Repeats (SSRs), are polymorphic loci present in nuclear and organellar DNA that consist of repeating units of 1-6 base pairs in length. They are typically neutral, co-dominant and are used as molecular markers which have wide-ranging applications in the field of genetics, including kinship and population studies. Microsatellites can also be used to study gene dosage (looking for duplications or deletions of a particular genetic region). Introduction One common… (More on Microsatellites)
