Q. Consider the following statements regarding cytoplasm transfer via somatic hybridization:

Statement I: Cytoplasm transfer that normally takes 6–7 years via backcrossing can be achieved in just one year using protoplast fusion.

Statement II: Iodoacetate is used to inactivate the nucleus of the recipient parent protoplasts.

Statement III: Irradiation of donor protoplasts is used to inactivate their nuclei.

Statement IV: The resulting cybrids contain the nucleus of parent A and mitochondria of parent B.
