Correct Matching
| Term | Definition |
|---|---|
| Inbreeding | Mating of related individuals (increases homozygosity) |
| Outbreeding | Mating of unrelated individuals (increases heterozygosity) |
| Panmixia | Random mating |
| Grading up | Pure-bred is obtained after 7–8 generations |
| Cross breeding | New breed is evolved; mating between different breeds within same species |
Note: Inbreeding = genetic assortative mating; Outbreeding = genetic disassortative mating. Grading up uses a pure-bred sire with local females generation after generation.
