Figure 1.

Illustration of the relative fitness comparisons made by Araki et al. (2007a,b) and the spatial and temporal opportunities for domestication selection to occur. Thin arrows indicate where a fish moves over the course of its lifecycle. The thick solid line illustrates where and when in the lifecycle selection could act to reduce the fitness of C[W × W] fish (captive progeny of two wild parents) compared to wild fish. The gray and dashed lines illustrate differences in the lifecycle (and hence opportunities for differential selection) of C[W × W] and C[C × W] fish, respectively. See text for details.
