• B. Cross- breeding
• C. Close breeding
• D. Line breeding

Answer 1

The correct option is B

Cross- breeding

During cross breeding, superior males of one breed are mated with superior females of another breed. Cross-breeding allows the desirable qualities of two different breeds to be combined. The hybrid offspring with desirable traits are chosen and are either used for commercial production or are subjected to some type of inbreeding and selection. Inbreeding helps in the development of stable breeds that may be superior to existing breeds. Many new animal breeds have been developed by this approach. For eg., Hisardale is a new breed of sheep developed in Punjab by crossing Bikaneri ewes and Marino rams
