Answer:
Correct Answer: C
Solution:
The transmission of traits from parents to offspring which occurs through substances present outside the nucleus and inside the cytoplasm is called cytoplasmic inheritance. The genes or factors present in the cytoplasmic structures which are capable of replication are called plasmagenes. The whole self-duplicating hereditary material of the cytoplasm is known as plasmon. Besides plastids and mitochondria, plasmagenes may also occur inside specific particles like alfa, beta and kappa.
