• C. ii and iii
• D. iii and iv

Answer 1

The correct option is A

i and iii

The correct option is A.

Explanation for correct option:

1. Plant hybridization involves the crossbreeding of genetically dissimilar parent plants to produce hybrids.
2. It generates heterozygous strains among the filial plant generations.
3. This helps improve the genotype of the crop and establishes the commercially vital traits of the crop.
4. Genetically modified crops are modified with desired traits.
5. GM crops are produced by the insertion of genes of the desired traits via hybridization.
6. These traits include disease resistance, herbicide resistance, pest resistance, and improved shelf life.

Explanation for incorrect options:

Option B, C and D.

1. Interspecific hybridization is the cross between two species of the same genus.
2. This helps explore the crucial genes present in the wild species for usage in cultivable species.
3. .Intervarietal hybridization is the cross between plants of two different varieties of the same species.
4. It is commonly used in crop improvement.

Final answer: The correct sentences are hybridization means crossing between genetically dissimilar plants and ntroducing genes of the desired character into a plant gives a genetically modified crop.
