Gay people can't have babies . . . or can they?

Via Atrios who got it from Signorile:

Scientists in Pennsylvania yesterday said they had turned ordinary mouse embryo cells into egg cells in laboratory dishes -- an advance that opens the door to creating "designer" eggs from scratch and, if repeated with human cells, could blur the biological line between fathers and mothers.

The work undermines the standard model of parenthood because the scientists made egg cells not only from female cells, but also from male cells, indicating that even males have the biological capacity to make eggs.

If the science holds true in humans as in mice -- and several scientists said they suspect it will -- then a gay male couple might, before long, be able to produce children through sexual reproduction, with one man contributing sperm and the other fresh eggs bearing his own genes.

The only problem with making the jump to the last paragraph that I see is what happens if an embryo has two "Y" chromosome? From what I know of biology/genetics (which admittedly is not much) I would suspect that the Y chromosome is a dominant, so it could be nothing except just another male, or possibly some sort of crazy uber-male. But then, nowhere in nature do we have examples of animals with two Y chromosomes (as far as I'm aware), so it could potentially have negative, unforeseen effects.

Still if this works, it would be such a punch in Santorum's face. Take that, face!

Update: Ha ha ha ha ha , the whole indenting of quotations works. (thanks to Ampersand for telling me how to do it) Now Raznor's Rants shall enter a new age of more easily readable quotations.
