Citogenetika je posebna oblast genetike koja izučava uzroke naslednih promena na nivou struktura i procesa u ćelijama, sa naročitim osvrtom na promene u hromozomima. Ova oblast povezuje dve zasebne nauke citologiju i genetiku.
Glavna koncentracija genetičkog materijala nalazi se u:
- jedru eukariotske ćelije
- nukleoidu prokariotske ćelije.
Pored jedra postoje i organele koje imaju sopstvenu DNK i ribozome, kakve su:
- mitohondrije - mitohondrijski genom
- plastidi - hloroplastni genom.
Kod prokariota van hromozoma se nalaze plazmidi i epizomi.
