What is meant by cytoplasmic inheritance ?

Explanation

DNA is the universal genetic material. Genes located in nuclear chromosomes follow Mendelian inherittance. But certain traits are governed either by the chloroplast or mitochondrial genes. This phenomenon is known as extra nuclear inheritance. It is a kind of Non-Mendelian inheritance. Since it involves cytoplasmic organelles such as chloroplast and mitochondrion that act as inheritance vertors, it is also called Cytoplasmic inheritance.
