Wearing your genes on your sleeves

^ A good way to describe sexual signalling.

Honest signalling is as I understand it, generally accepted

In a species that has a sexually selected trait, a long tail or bright plumage is hard to lie about. Because you either won't have the nutrition to produce the 'fake' trait or you'll die while producing it. (although im sure exceptions to this must occur).

In a species without secondary sexually selected characteristics where sexual conflict occurs lying is almost assumed because no one can 'prove' whether they are good or not, therefore the system is open to manipulation. e.g. Drosophila seminal proteins, manipulate the females reproductive system to benefit the male and stop other males mating with her.

If recessive mutations can be assumed to be 'invisible' will there be honesty or lying. Or because the costs of heterozygous recessive mutations can be minimal or most commonly nothing does nothing occur. Is it all neutral.
