If we consider the aggregate of an entire generation of such offspring it is clear that the total reproductive value of the males in this group is exactly equal to the total value of all the females, because each sex must supply half the ancestry of all future generations of the species.
如果我们考虑整整一代的这样的后代的繁殖价值的总和，那么很显然此群体内所有雄性成员的总价值和所有雌性成员的总价值是相等的，因为每个性别必定为其物种的所有未来后代贡献一半的血统。
