Question

Which one out of the following is correct sentence?
(i) Hybridisation means crossing between genetically dissimilar plants.
(ii) Cross between two varieties is called as inter specific hybridisation.
(iii) Introducing genes of desired character into a plant gives genetically modified crop.
(iv) Cross between plants of two species is called as inter varietal.

• A. (i) and (iii)
• B. (ii) and (iv)
• C. (ii) and (iii)
• D. (iii) and (iv)

Answer 1

The correct option is A (i) and (iii)

The crossing between genetically identical plants to produce a new variety, that is hybrid is called hybridization. Crossing may be between two different varieties (intra varietal cross breeding), between two different species of some genis (interspecificcrossbreeding) and between different genera (intergenericcrossbreeding). Genetically, modified crops can be produced by insertion of genes with desired traits by the process of hybridization.

Therefore, the correct answer is option A.
