Organellar DNA (oDNA) is DNA contained in organelles (such as mitochondria and choloroplasts), outside the nucleus of Eukaryotic cells. The traits encoded by this type of DNA, in animals, generally pass from mother to offspring rather than from the father. This is due to the ovum provided from the mother being larger than the male sperm cell, and therefore has more organelles, where the organellar DNA is found.

Although maternal inheritance is most common, there are also paternal and biparental patterns of inheritance that take place. The latter two patterns of inheritance are found most often in plants.
