During the explanation of the significance of several breeding techniques

During the explanation of the significance of several breeding techniques, teacher makes a statement about inbreeding depression and suggested a solution for it. Pallavi became very curious about knowing all this and asked certain questions to his teacher.
(i) Why is breeding required?
(ii) What is the significance of improved variety?
(iii) What is interspecific hybridisation?
(iv) What values are shown by Pallavi as a science student?

(i) Breeding is a necessary process among organism through which the progeny of animals are produced with a variety of improved characters (under controlled conditions).
(ii) Improved variety of animals and plants have higher and better quality of products.
(iii) The hybridisation process in which animal of one species is hybridised with animal of other species is called interspecific hybridisation.
