Inbreeding mates animals of the same breed for 4-6 generations, raising homozygosity; while it can expose harmful recessive genes and cause inbreeding depression if overused, careful inbreeding followed by mating with superior unrelated animals of the same breed restores fertility and yield.
Step 2. Outbreeding mates unrelated animals with no shared ancestry for 4-6 generations, and takes three forms: out-crossing (unrelated animals of the same breed, suited to raising below-average producers), cross-breeding (a superior male of one breed with a superior female of another, producing hybrid vigour), and interspecific hybridization (mating across two species, as in the mule).
Step 3. Artificial insemination injects collected semen into a selected female's reproductive tract, raising conception rates, avoiding disease transmission, using semen from injured but valuable bulls, and enabling breeding between geographically distant superior animals. …
