Cytoplasmic inheritance is the type of inheritance in which the genes that are present outside the nucleus, in the cytoplasm are transmitted. It is also known as extra-chromosomal and extra-nuclear inheritance. This kind of inheritance occurs in the eukaryotic organisms and the organelles which are widely involved in this are those which have their own DNA i.e. mitochondria and chloroplasts.
As they constitute their own DNA, they are also termed as self-replicating organelles. The genes that are present in these organelles tend to play a significant role in normal cellular functions. Their DNAs replicate themselves independently of the cell division. The recombination of genomes does not occur in these organelles due to their independent nature.
