>Even given the success of such an
outcome - what would be the chances of survival of the offspring,
remembering that rainbows school for protection from predation I
wouldn't like to stand out in a crowd.
Any rainbow can turn silver in which case they would all look alike.
Rainbows don't always have strong colour in the wild and many species
have silvery or plain females. It would be easy for a male to mimic
that. Also, many species have males that will mimic females to get in on
the act when the males are spawning with one or more females? I don't
believe anyone has looked for this and I would be surprised if it didn't
occur at least in some populations.
