Answer 2

ANSWER:

Cytoplasmic control and sterility  is found in rice because of mitochondrial and nuclear interaction

EXPLANATION:

Rice is very important crop. It is used in industrial feedstock and also for the bioproducts. Male sterility is useful for the hybrid seeds development.  The cytoplasmic control and sterility are found in rice. It is the result of mitochondrial and nuclear interaction.

Sterility means the failure of plant to produce gametes. The cytoplasmic control can be controlled by an extranuclear genome. It is achieved by the mitochondrial genome which is present in the rice plant.
