In plants, male sterility can be regulated through nuclear genes, cytoplasmic factors, or a combination of both. Which of the following represents the three mechanisms responsible for male sterility?

1. Male sterility caused by genetic factors
2. Male sterility caused by cytoplasmic factors
3. Male sterility caused by both genetic and cytoplasmic factors
4. In maize, genes controlling cytoplasmic male sterility are found in the nucleus or mitochondria

Correct answer: Male sterility caused by both genetic and cytoplasmic factors

Solution

The correct choice is the one describing combined genetic and cytoplasmic control, because male sterility in plants can be governed by nuclear genes, cytoplasmic factors, or their interaction. Among the options, only the combined mechanism matches the full set of causes.
