Competition of males for females occurs because each male has enough sperm to fertilize the eggs of many females, while the sex ratio of most species is 1:1.

Or, a female preference for a male trait is under selection because her mate choice affects her survival or fecundity (e.g., if males provide resources for the female, or if some males are more efficient at fertilizing her eggs).
Biological Evolution and Statistical Physics
Scharf (as cited on page 91 of Stauffer et al 2006) offered the additional argument of pre-selection: Only the fastest sperm cell can fertilize the egg cell, and cells with bad mutations may move slower and thus are less likely to enter the egg cell.
