Final answer:
Intralocus sexual conflict refers to the conflict between males and females within a species over traits that have different effects on their reproductive success and survival. This conflict can explain the male-female health-survival paradox, where males often have shorter lifespans and higher mortality rates compared to females. Resolving this paradox involves finding a balance between traits that enhance reproductive success and those that enhance survival.
Step-by-step explanation:
Intralocus sexual conflict refers to the conflict between males and females within a species over traits that have different effects on the reproductive success of each sex. This conflict arises because traits that enhance the reproductive success of one sex may be detrimental to the other sex. The male-female health-survival paradox refers to the observation that in many species, males often have shorter lifespans and higher mortality rates compared to females. Resolving this paradox involves understanding how intralocus sexual conflict influences the health and survival of males and females.
For example, in some species, males may have traits that make them more successful in competing with other males for mates, but these traits may be costly in terms of health and survival. On the other hand, females may have traits that enhance their survival, but may reduce their reproductive success. Resolving this conflict requires a balance between the selective pressures favoring traits that enhance reproductive success and those that enhance survival.
