Sounds like the peacock conundrum. A peacock with a big tail has better mating success, but makes it less capable of escaping predators. Perhaps a brightly coloured guppy is too easily spotted by predators and most simply do not live long enough to breed, while the dull ones do.

It's apparently not the orange per se that drives female preference http://www.mendeley.com/research/algald ... the-guppy/

Assume dull is recessive - Mendelian genetics says even 2 oranges could produce a dull.

Jorge: could be, but if you were selecting the orange ones all the time, you would get population of only oranges in some time.

However, the question is, what is preferable for females? I would guess to be dull and thus these would keep the dull gene in ppulation.

Cis or trans? That's what matters.
