I can't think of a sexually reproducing organism that *doesn't*
have a haploid life history stage upon which selection can act.
I'm willing to hear about some exceptions, though :)

So, how are organisms with primarily haploid life cycles 
playing by different rules than organisms with relatively
brief haploid stages?  It seems to me to be a difference
of degree, not of kind.
