The correct answers are selective breeding, hybridization, induced mutation.
The classical biotechnology deals with the use of techniques such as selective breeding, hybridization, and induced mutation. The above procedures drive the classical biotechnology. Some of the recent industrial development programs were successful using these techniques. Selective breeding involves the breeding of desired characters of plants or animals to get the hybrid which has the desired characters. Hybridization is the process of breeding of different organism to get the hybrid. Induced mutation by UV rays and chemicals, is also used to obtain various substances such as penicillin antibiotic from mutated fungal stream.
