 Parental investment is when either parent cares for eggs or offspring resulting in increased offspring fitness.Though intuitively one might assume that since providing care to offspring would provide indirect genetic benefits to both parents, there would not be much sexual conflict; however, since neither is interested in the other's genetic fitness, it is more beneficial to be selfish and push the costs of parental care onto the other sex.Therefore, each partner would exert selection on the other partner to provide more care, creating sexual conflict.
