Mother's Day and the gay gene

What do Mother's Day and the gay gene have in common? A lot. Guess what, my son probably got the X chromosome with the genetic DNA marker called Xq28 from me! That's why he is gay. Since girls get an X chromosome from each parent, some scientists say there's "a battle between the X's," and it's not clear--and they say that the X's are not in agreement. Hey, my late-husband and I were always in agreement. Clearly, the scientists agreed that more research needs to be done on lesbian women.
I'd love to volunteer my DNA for testing of the gay gene. That fascinates me. For now, I'll take credit for the gay gene my daughter received, too. These and many other studies are not absolute, but they certainly shed light on what I've always believed--there is a gay gene.
Most studies, however, have been done on males. Not surprisingly, research money is not readily available to study the gay gene, because it's a politically volatile issue and some scientists fear researchers would work to eradicate the gay gene.
Studies done on gay brothers and identical twins have had successful outcomes in identifying good old Xq28.
Other studies done on the hypothalamus of the brain connect it to sexual orientation as well. This was discovered in work with sheep, where 8 percent of domestic rams are exclusively interested in sex with other rams. When these rams were studied, the comparison in the size of the oSDN--a densley-packed cluster of neurons in the hypothalamus of their brains--was similar to that found in the brain scans of gay males in the study. The hypothalamus regulates body temperature, blood pressure and sexual behavior.
Many researchers are themselves gay and lesbian and devoted to this biological research. It is important work for all those who are gay and for those of us who have parented gay children.
So, as Mother's Day approaches, we have even more reason to be the voice of support for gay marriage. It's our responsibility mothers!
