Question

Briefly write about only two:

(a) Out breeding,

(b) Cross breeding,

(c) Controlled breeding.

Answer 1

(a) Outbreeding:

It is the process of breeding of the unrelated animals. The animals that are bred are the same breed but they do not have common ancestors for 4-6 generations.

Also, animals of different breeds or different species are used for breeding.

(b) Crossbreeding:

It is the process of the crossing of superior males of one breed with superior females of another breed.

By this type of breeding desirable qualities of two different breeds are obtained in the hybrid. The hybrids can be commercially exploited for production.

It can also be used for inbreeding. By this method, many animal breeds have been produced.
