Basically all they are saying it is the female's oven (uterus) that is responsible for baking the cake properly. They dont say anything about the ingredients supplied from both mom and dad (genetics). Which is good to know because there is nothing about genetics involved in this particular study. Sorry for the talk down.Your explaination would be one of the first things you would query the authors about.
The 55 to 60 thing v. the male would be something I would have to say why not 50/50
Oops I just realized you did not even ask about the uterus, you just said you dont buy it.

you run up against the nature vs. nurture debate which is really what they are talking about IMO when they say the mare contributes more...not much different than a woman who goes to the sperm bank and then raises a child on her own....she obviously has a greater bearing on the childs success than the father despite equal genetic contributions.
