Question
Give an account of out-breeding of animals.
Solution
Out-breeding. It involves breeding of the unrelated animals which may belong to same breed but having different ancestries; or between different breeds (called cross-breeding) or between different species.
Out-breeding is of following types :
(a) Out-crossing. In this type of breeding, the animals of same breed, but not having common ancestry on either side of pedigree for about 4 to 6 generations are crossed.
(b) Cross-breeding. It involves interbreeding of superior males of one breed with superior females of another breed to produce hybrid animals having commercial importance.
(c) Inter-specific hybridisation. In this method male and female of different related species are mated.
