If they have the DNA that they believe might belong to the killer, shouldn't they know gender? Why would they test everyone in the family? Could they even get that broad a warrant? I know it's just a show and they did it to have more suspects but gender from DNA is one of the basics... That said, I will stop looking to deeply and just try and enjoy the mystery.
I think it's because the DNA matching test is looking at a number of gene markers, not the entire chromosome that would identify gender.

On a fresh blood stain or saliva stain, surely they could. On the old stain on the belt, I assume they would be working with degraded fragments of DNA, and may not have enough to do multiple tests. Since testing for Y-chromosome DNA is only going to rule out about half the population (or about half the family in this case), it could be considered a waste of the recoverable DNA.
did they ever get a DNA of Mitch?
Did they test that Jersey of his? with the bloodstain?
