Given the arc that Alex has in FC, it doesn't strike me as being very likely that he'd abandon Scott - assuming that he IS in fact Scott's father - to the kind of existence he himself had to endure as a child. It also doesn't strike me as being very likely that Alex would father a child with someone who wasn't a fellow mutant, or that he wouldn't have told Xavier about Scott and asked him to look after the boy if he weren't able to, which would've likely meant that Scott would've already been at the school and therefore out of the reach of William Stryker, which we know wasn't the case.
