I have a few questions of my own erm in, in doing it and erm   was er when you say that, that males  had males   parental investment erm I was wondering how  they, how can a male when the male decides to desert how can they be certain if the female is going to take care of the offspring, because I was wondering if erm if  probability like the  based by their genes it doesn't matter if one female doesn't take care of the offspring because they  produce  more offspring
