According to Trivers' theory of parental investment, the sex that invests more in the offspring (in this case, the females) will be more discriminating in choosing a mate. This is because the investment in offspring is a significant cost, and selecting a mate with good genes or who can provide additional resources can increase the offspring's chances of survival.
