Inter-Simple Sequence Repeat

I-SSR, o Inter-Simple Sequence Repeat, o Inter-microsatelliti, sono una tipologia di marcatori genetici (o marcatori molecolari) dominanti, multilocus, poco utilizzati.^[1] Essi differiscono dai marcatori microsatelliti in quanto i loro primer sono ancorati a microsatelliti adiacenti, amplificando la regione tra loro compresa.^[2]

In quanto multilocus, consentono di saggiare più loci per ogni analisi; in quanto dominanti, non consentono la distinzione genotipica (tra omozigote ed eterozigote) in una certa posizione.^[3]
