Question

DNA of mitochondria shows which of the following?

• A. Internuclear inheritance
• B. Intranuclear inheriance
• C. Mitochondrial inheritance
• D. Cytoplasmic inheritance

Answer 1

The correct option is D Cytoplasmic inheritance

The mitochondria contain DNA which possess genes that are essential for the normal mitochondrial functioning. The nuclear DNA is inherited from both parents along with a recombination of genes. The mitochondrial DNA is inherited from the mother which is present in the cytoplasm of the ovum. There is no genetic recombination in the mitochondria DNA which is inherited from mother to offspring. The transmission of genes outside the nucleus and from the cytoplasmic organelles is known as cytoplasmic inheritance.

Thus, the correct answer is option D.
