there are some cases where the parental investment is switched,有这样的例子 亲本投资转换了 -
some cases where it turns out--这些研究结果发现 -
where the males end up with more investment雄性最终比雌性 -

that in these cases you should get an asymmetry.在这些案例中会获得结果是不对称的 -

and plugs them into his bloodstream.再把它们塞进自己的血管中 -
The females shoot off.而雌性跑了 -
They have less of an investment than the males.她们比雄性付出少 -
In this case, you would predict, as is true,在这种情况下 你能预测 也是真实的
