Correct.
Since I happen to be educated in this realm of biology I'll expand upon this further. What we are discussing here might fall under the realm of fitness of individuals. Though biologically speaking, fitness usually is referring to a trait common among a group rather than a few individuals. The allele that grants red coloration of the feathers found on the male birds head that makes female birds go absolutely bonkers for.
Male individuals gain fitness by having as much offspring as possible with as many partners as possible, but they only gain fitness when those offspring have offspring of their own.
Females gain fitness in a different way. They cannot gain fitness by having as many offspring as possible as it would be detrimental to their health. Instead, since as described above males are always looking for partners, the females gain fitness by acquiring a mate that they believe has the best traits and having its offspring.
That is the concept in the animal kingdom. It gets understandably more complicated when applied to humans and you have biology vs sociology/psychology in conflict.
