“God Doesn’t Make Mistakes”

Or “God only make male and female.”

Or “If they have a penis then they are a man”

Or “If they have XY chromosomes they are a man and if they have XX chromosomes they are a women”

I sure you all have read comments like these and my answers to them are, you are right God doesn’t mistakes and for the other three “Oh really?” Maybe you should pick up a biology book that was printed after 1960. Genetics has made giant leaps in understanding chromosomes and DNA that open up huge possibilities.

There is an article in the New York Times about how scientists are finding that we may have more than one set of DNA in our body and it is much more common than was originally thought.

DNA Double Take

From biology class to “C.S.I.,” we are told again and again that our genome is at the heart of our identity. Read the sequences in the chromosomes of a single cell, and learn everything about a person’s genetic information — or, as 23andme, a prominent genetic testing company, says on its Web site, “The more you know about your DNA, the more you know about yourself.”

But scientists are discovering that — to a surprising degree — we contain genetic multitudes. Not long ago, researchers had thought it was rare for the cells in a single healthy person to differ genetically in a significant way. But scientists are finding that it’s quite common for an individual to have multiple genomes. Some people, for example, have groups of cells with mutations that are not found in the rest of the body. Some have genomes that came from other people.

I had heard of people who had underwent bone mallow transplant having two blood types and also I heard of a type of Chimerism where a person has two sets of chromosomes because their body adsorbed their sibling while still in the womb which happens sometimes with twins.

One woman discovered she was a chimera as late as age 52. In need of a kidney transplant, she was tested so that she might find a match. The results indicated that she was not the mother of two of her three biological children. It turned out that she had originated from two genomes. One genome gave rise to her blood and some of her eggs; other eggs carried a separate genome.

The article goes on to say that this can happen also to the mother during presence,

Women can also gain genomes from their children. After a baby is born, it may leave some fetal cells behind in its mother’s body, where they can travel to different organs and be absorbed into those tissues. “It’s pretty likely that any woman who has been pregnant is a chimera,” Dr. Randolph said.

The article said that the researchers are looking into if this is a factor in more common diseases, like schizophrenia. This I think gives rise to some interesting possibilities.

Could this possibly a cause of trangenderism? Think of it, if the section of the brain has some foreign female DNA and that part of the brain control our gender identity; could that result in us being transgender?
