When inbreeding depression occurs, a genetically unrelated individual is mated with the animal to introduce genetic variability and remove homozygosity. In this case either outbreeding or crossbreeding may be carried out. Is there any preference for either technique over the other? Out-breeding here refers to mating between two individuals in the same breed, but no recent common ancestors. Cross-breeding refers to mating between two individuals of different breeds entirely.

  • $\begingroup$ can you clarify language? Is it that outcrossing is mating between different populations, whereas crossbreeding is mating between members of inbred populations? E.g. mating between european and asian peasants versus mating between members of european and asian royal families. $\endgroup$ – aaaaaa Sep 6 '15 at 5:00
  • $\begingroup$ this article mentions both outcrossing and crossbreeding. Language seems confusing to me $\endgroup$ – aaaaaa Sep 6 '15 at 5:01
  • $\begingroup$ I don't think there is any accepted clear definitions of outbreeding vs crossbreeding. Therefore, definitions should be provided in the post. $\endgroup$ – Remi.b Sep 6 '15 at 5:42
  • $\begingroup$ @Remi.b my point exactly. Although, broadly, if you cross inbre(a)d species, you get less variation than crossing more wild-typish (forgive me) animals $\endgroup$ – aaaaaa Sep 6 '15 at 7:25

Inbreeding depression can be overcome by the following ways : 1. Out breeding- the breeding of animals which are unrelated to each other and do not have come ancestors for 4-6 generations 2. Out crossing- mating done with the animals osf same breed but after 4-6 generations 3. Cross breeding- superior male mated with superior female of another breed 4. Interspecific hybridisations- male and female animal of two different related species

  • $\begingroup$ This answer is not addressing the actual question which was: which of these techniques is preferred and why? $\endgroup$ – Flo Aug 24 '17 at 8:30
