Detailed explanation-1: -(i) Hybridization means crossing between genetically dissimilar plants. (ii) Cross between two varieties is called as interspecific hybridization. (iii) Introducing a gene of desired character into a plant gives genetically modified crop.
Detailed explanation-2: -Hybridization refers to crossing between genetically dissimilar plants.
Detailed explanation-3: -Crossing between different varieties is known as intervarietal hybridisation. Crossing between different species of the same genus is known as interspecific hybridisation. Crossing between different genera is known as intergeneric hybridisation.
Detailed explanation-4: -The cross performed between two plants belonging to different species (having different characters) is referred to as hybridization as both the plants are heterozygous for two different traits. Hence (i) is correct.
Detailed explanation-5: -Hybridization is defined as the process of interbreeding between two genetically divergent individuals or two individuals of different species.
