Q. Kappa particles indicate :
- Nuclear inheritance
- Cytoplasmic inheritance
- Mutation
- Nucleo-cytoplasmic inheritance
Solution :
Correct option : B Kappa particle indicates cytoplasmic inheritance. It is an inheritable cytoplasmic symbiont which occurs in some strains of the ciliate Paramecium. The species which has kappa particle is known as a killer. It is a fuelgen positive particle which allows the inheritance of maternal traits through the cytoplasmic inheritance. The cytoplasmic inheritance is mainly caused due to the expression of genes present in the extra-chromosomal segments. So, the correct answer is option B.
