#Plant Biotechnology
Q. Assertion: In plant breeding, cytoplasm transfer via somatic hybridization is significantly faster than conventional backcrossing.
Reason: Protoplast fusion can achieve in one year what typically takes 5–6 years through the backcrossing method.

#Plant Biotechnology
Q. Assertion: Symmetric hybrids allow for the transfer of genes between species that are sexually incompatible.
Reason: Somatic hybridization bypasses the requirements of pollination and fertilization, enabling fusion between even completely sterile lines like monoploids.

#Plant Biotechnology
Q. Assertion: Cybridization enables the creation of unique organelle combinations that cannot be produced through sexual reproduction.
Reason: Somatic fusion allows the mitochondria of one species to be combined with the chloroplasts of another, often resulting in recombinant organellar genomes.

#Plant Biotechnology
Q. Assertion: Somatic hybridization is currently the primary method used for the commercial improvement of all major cereal and pulse crops.
Reason: Techniques for protoplast isolation, culture, and fusion are not yet readily available for many important cereals and pulses.

#Plant Biotechnology
Q. Assertion: Chromosome elimination in somatic hybrids is a highly predictable process used for precise gene mapping.
Reason: Genetic instability is a common limitation in somatic hybrids, particularly in wide interfamilial crosses, often resulting in abnormal or sterile plants.
