If you have ugly children, you're beautiful

Sexy males sire dowdy daughters and attractive females bear insipid sons – in fruit flies, at least.

This perverse pattern of inheritance may be one reason why not all individuals are highly attractive. It may even help explain why many of the showiest sexual displays are found in birds and butterflies, rather than other organisms.

The paradox arises because many of the traits that enhance a male's reproductive success are detrimental to female success, and vice versa. For example, female flies that devote a lot of time to feeding may have more energy to put into egg-laying, whereas males may do better spending more of their time mating instead.

So, let's hope the converse isn't true: If you have beautiful offspring, does that mean you're ugly?
I have three beautiful children, I guess I know why now.
