Q. Assertion (A): The main purpose of producing asymmetric hybrids is the introgression of specific desirable genes into another species.

Reason (R): Asymmetric hybridization allows selective elimination of chromosomes from one parent while retaining specific genes.

Q. Assertion (A): Asymmetric hybrids often contain multiple genome copies of the non-irradiated parent.

Reason (R): Irradiation of one parent leads to extensive chromosome breakage and deletion.

Q. Assertion (A): After repeated backcrossing of asymmetric hybrids with N. plumbaginifolia, plants with a diploid N. plumbaginifolia genome and a few A. belladonna chromosomes were recovered.

Reason (R): Backcrossing helps eliminate unwanted alien chromosomes while retaining selected genes.
