Question

Which is not an example of cytoplasmic inheritance?

• A. Female sterility in maize
• B. Sigma particle inheritance
• C. Kappa particle inheritance
• D. Plastid inheritance

Answer 1

The correct option is A Female sterility in maize

Cytoplasmic male sterility is total or partial male sterility in plants as the result of specific nuclear and mitochondrial interactions. Male sterility is the failure of plants to produce functional anthers, pollen, or male gametes. Cytoplasmic male sterility is an important part of hybrid maize production. But it remains unaffected in female sterility in maize; but only related to male sterility in maize.
All other options are examples of cytoplasmic male sterility.
