cytoplasmic inheritance

or

extranuclear inheritance

the control of certain characters by genetic factors located in the cytoplasm of EUKARYOTES. These cytoplasmic mechanisms can show themselves as general ‘maternal’ influences (since the female gamete contains more cytoplasm than the male) as in the control of shell coiling in the snail Limnaea. DNA has also been located in several cytoplasmic organelles, such as a MITOCHONDRION or a CHLOROPLAST, which can replicate and function independently of the nucleus.
