AnswerC.
To make a plant correct
D.
None of the above
Answer: Option B
Solution
Answer: Option B
Solution:
A restore gene is needed to bring fertility in the male sterile plant.The restorer-of-fertility (Rf) nuclear genes have been used to rescue the damage induced by mitochondrial DNA rearrangements.
Rf is a dominant allele for restoring male fertility and rf is its recessive allele inducing male sterility, in the presence of a male-sterile cytoplasm, S. N refers to normal cytoplasm that gives male-fertile plants in the presence of either the Rf or rf allele in the homozygous state.
