I guess this is somewhat a dumb question but as a percentage the differences between xy and xx account for how much genetic material? Is is less than 1%?

It is not a dumb question, since many genes on the Y chromosome do not function any more. Remember, though that on the X chromosome is deactivated in females. So, it is probable a small percentage difference, if any. A gene does not care what sex it is in as either sex is reproductively successful.
Perhaps some functional biologist will come along to give a precise answer.

Males and females are homo sapiens. All genetic material is essentially the same. The genetic differences between a male and female would be really no more than the differences between two females or two males.

i cant express it in terms of percentage but can tell u that-
at the end it boils down to a diff of one X and one Y....now this X is inactivated due to dosage compensation and the Y has very very few genes....the inactivated X is not totally inactivated...the regions homologous to the active counterpart of Y are activated....only these regions differ but actually they share a homology so the diff is even smaller...
functionally many autosomal genes may differ...there are some se limited (not linked) genes which gets activated in only a specific sex
