OUT BREEDING

Out breeding is the mating of animals which are less closely related to each other than the average of the population. Its general effects are the opposite of those of inbreeding. Out breeding increases the heterozygosity of the individual. The maximum practical usefulness of out breeding systems is the production of animals for market. Out breeding systems are broadly classified as follows:

1. Out crossing
2. Top crossing
3. Line crossing
4. Grading
5. Crossbreeding
6. Species hybridization
