One of the breeding techniques useful to eliminate harmful recessive genes by selection is
Artificial insemination
Outbreeding
Inbreeding
MOET

Inbreeding
When breeding is done between animals of the same breed for 4-6 generations, it is called inbreeding. Inbreeding is necessary if we want to develop a pure line of any animal. It exposes harmful recessive genes that are eliminated by selection. It also helps the accumulation of superior genes and the elimination of less desirable genes.
