Solution:

Somatic hybridization is the process in which isolated protoplasts from two different varieties of plants are fused. Cross hybridization is combining desirable characteristics from two plants by the method of cross pollination. Mutation breeding is breeding of plants in which genetic variations are created by gene mutation. It involves cross hybridization. Micropropagation is the process of growing thousands of plants in nutrient medium using their shoot tips which are free from viruses.
