I was reading this story earlier ---> http://www.npr.org/templates/story/story.php?storyId=4227604 I was actually thinking, it's weird that science hasn't found a way for homosexuals to have kids yet with both of their DNA. Of course it's not natural but lots of things are possible with science. I thought years ago they would have found a way to fertilize egg cells with a cell from another females body (stem cells). I read so much about it. Even about mice being created by 2 moms and 2 dads (research it). I mean, if medicine was created to help you when your sick, there's got to be endless possiblities. Apparently in Belguim they have even found a way to choose your babies sex. What do you think of this? Here's another link: http://news.bbc.co.uk/1/hi/health/1431489.stm It could also help couples where men cannot produce sperm or women who's egg cells don't work (Like Chandler and Monica in friends). http://www.abc.net.au/worldtoday/stories/s327396.htm

I don't believe it's so much that science can't find a way to combine the DNA of two men or women as it is science doesn't have the incentive. It probably would only take time to figure out how to create an egg without it's own DNA, then add in the DNA of two men, and make sure the two Y chromosomes don't pair (you need an XX or XY pair), but the controversy it would cost, wouldn't be worth it, and I'm sure nobody is willing to pay the money needed to start such a project. Will most likely happen in the future when homosexuals are more widely accepted.

Unfortunately, it's much more complicated than that! Research Is being done as we speak. The main issues include epigenetic differences, which basically means modifications of the DNA (not affecting the sequence) that control the way genes are expressed. Many genes come pre-programmed with these changes. Also, some genes are imprinted, meaning they are only expressed from the dad's chromosome, or only from the mom's. So 2 females would lack the paternally expressed genes, and vise-versa. We don't know how to re-program those changes at this point. It has been done in mice, using 2 females, but it very difficult and has an extreme high failure rate, and if I remember correctly, the resuling offspring were not completely healthy. It is possible that these technologies may be present someday, but not for some time!
