0 a situation in which plants, animals, or people are produced by breeding between closely related plants, animals, or people: --
Moreover, although unlikely, one may argue that the target fish could be immunosuppressed due to inbreeding.
There is also much to be learned about recruitment of parasites by their various hosts, inbreeding within local populations and dispersal patterns.
Male-male competition magnifies inbreeding depression in wild house mice.
Higher proportions of ambiguous offspring than expected under random mating might reflect inbreeding by some parents whereas lower proportions might reflect outbreeding.
Other forms of non-random mating should also be considered, especially in vertebrate hosts, such as homogamy or biparental inbreeding.
The lines were fully viable and showed no signs of inbreeding depression.
From this study there does not appear to be an obvious optimum inbreeding rate as far as mean viability is concerned.
In these models, inbreeding depression is assumed to affect zygote-to-adult viability only.
