Introduction:
Cytoplasmic inheritance or no chromosomal extranuclear inheritance is the passage of traits from parents to offspring through structures present inside the cytoplasm of contributing gametes.The genes or factors controlling cytoplasmic inheritance are called plasma genes or extranuclear genes.They are called plasmon.plasmon genes occur in plastids, mitochondria , plasmids and some special particles like Kappa particles , sigma particles etc .In higher organisms cytoplasmic inheritance is also called maternal inheritance because the zygote receives most of its cytoplasm from the ovum.Therefore, cytoplasmic inheritance is usually uniparental . Reciprocal crosses donot yield the same result.
