Q. Statement I: In the cybrid approach, iodoacetate is used to inactivate the nuclei of the recipient strain (Parent A). 

Statement II: Irradiation is used to inactivate the nuclei of the donor strain (Parent B) to ensure only its cytoplasm is transferred.

Q. Statement I: In the fusion product described, the mitochondria are always derived from the donor strain (Parent B).

 Statement II: The chloroplasts in the resulting regenerants must always come from the recipient strain (Parent A)

Q. Statement I: Fusing tomato protoplasts with irradiated Solanum acaule protoplasts produced plants that were morphologically identical to Solanum acaule. 

Statement II: The resulting tomato regenerants exhibited Cytoplasmic Male Sterility (CMS), which was inherited maternally.

Q. Statement I: Protoplast fusion can be used to develop male sterile lines even between sexually incompatible species. 

Statement II: CMS lines developed through this method cannot be used with traditional CMS restorers.

Q. Assertion: Cybrids can be produced by the irradiation of protoplasts from one of the fusion parents. 

Reason: Irradiation effectively inactivates the nucleus of the donor protoplast, allowing only its cytoplasm to contribute to the fusion product.
