A) Tissue culture
B) Genetic engineering
C) Inbreeding
D) Ikebana
Correct Answer: B
Solution :
Genetic engineering involves the isolation of specific genes, making copies of genes and their transfer to target genomes through a suitable vector. Through this technique, breeders are able to transfer a gene for pest resistance, nutritional quality cold/hot resistance, to a plant directly from a wild relative or even from an unrelated species. Thus, the genetically modified, desired breed can be developed in any plant. Tissue culture is the technical method of vegetative propagation, involves cloning through which a large number of virus-free plantlets can be produced in a limited space (in vitro). It is applicable for the formation of genetically identical plants, multiplication of sterile hybrids, development of new hybrids, etc. Inbreeding is mating of individuals closely related by ancestry. It is used in developing pure lines or homozygous lines and is useful in self-pollinated plants. Ikebana is a method of flowering arrangement in Japan.
