In a group without exogamy, selection for the group is selection for those genes responsible for the complex phenotype that is the group, in a similar but less strict way. This is true even with sufficiently minor exogamy.

Right, but then you don’t need a mechanism other than genetic selection. Because that’s what is typically meant by group selection: that there is an additional selective mechanism that exists aside and apart from genetic selection.

Maybe we are talking past each other then. Because to me group selection is a type of genetic selection.

Then we are in agreement. Typically, group selection is not meant in that way, though. Just an FYI.
