In breeding refers to the breeding between cattles which have same ancestors for 4-5 generations whereas the opposite stands true for out breeding.... but i m not very sure of this answer so u might as well confirm it

When breeding  is between animals of the same breed it is called inbreeding
Superior males and superior females of the same breed are identified and mated in pairs.

Inbreeding increases homozygosity.

Inbreeding exposes harmful recessive genes that are eliminated by selection.

It also helps in accumulation of superior genes and elimination of less desirable genes.


Crosses between different breeds are called outbreeding.

Out breeding is of three types-

1. Out crossing- Mating of animals within the same breed, but having no common ancestors on either side of their pedigree up to 4-6 generations is called outcrossing and the resulting  offsprings are called out cross.

2. Cross- breeding— Mating of superior male of one breed and superior female of another breed is called cross breeding. Desirable qualities of two breeds can be combined by this process. Hisardale is a new breed of sheep developed in Punjab by crossing Bikaneri ewes and Marino rams.

3. Interspecific hybridization- the process in which male and female of different species of animals are mated is called interspecific hybridization.
