Zoology - Principles of Inheritance and Variation Question with Solution | TestHub

Cytoplasmic inheritance or non chromosomal (extranuclear) inheritance is the passage of traits from parents to offspring through structures present inside cytoplasm of contributing gametes. The genes controlling cytoplasmic inheritance are called plasma genes or extra nuclear genes. These occur in plastids, mitochondria, plasmids. Cytoplasmic inheritance is usually uniparental. It is also called maternal inheritance as zygote receives its cytoplasm from ovum.
