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: 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.

#Plant Biotechnology
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.
