Problem is, it's been a few years since I took biology and I'm not sure about the plausibilty of it so here goes...
The basic story concept is to look at the possible applications and consequences if we could produce test-tube babies without donor sperm or eggs.
The process, as I concieve it would be like this:
A DNA sample is provided: sample could be from hair, saliva, blood, etc. Anything that contains DNA.
The DNA is extracted from the sample.
DNA is inserted into a "blank" genetic cell (an egg or sperm that has been stripped of its DNA and distinguishing characteristics). The DNA in the blank cell is used to code chromosomes and create a gamete (egg or sprem) that can be used for reproductive purposes. -- Heavy use of Handwavium pellets here...
So essentially, as long as you have a DNA sample, you could have anyones baby. You want to have Brad Pitt's child, all you need is a hair with an intact folicle or a discarded bandaid...
So my question to those who know more about these things than me, with the right amount of handwavium, does this sound remotely plausible?

You wouldn't be having Brad Pitt's child, because you wouldn't be contributing to the genetic code. You would be having Brad Pitt II.

You might need to give us some info on why this needs to happen:
quote:
I want the application to be that you only get a gamete which would be a part of artificial insemination with your own gamete and then implanted in either yours or a serogate womb (if you are man who wants the child).
Cloning would do the same thing with one less step.
Anyway, Robyn, I think you've got something you won't need much handwavium for. Just take the new cell with Brad Pitt's DNA and make it undergo meiosis (cell division that doesn't duplicate the chromosomes), and get a gamete that's like a regular human one. I remember from biology the process for forming eggs from an initial egg that's got all the chromosomes; I assume sperm are similar.
I can see room in that for using a synthetic cell, since most other types of cells aren't properly set up for meiosis. You also have to "reset" the DNA so that it isn't doing anything else (i.e. trying to make proteins) when you trigger meiosis. You'll have to handwavium those bits a little, but as long as you say things like "meiosis induction", people will think that it's close enough.
Your spouse dies before the two of you can have children. Using a DNA sample from a hair folicle from his/her brush, a gamete is created and combined with your own so you can have a baby.
Animal breeding. Race horses, pure-bred pets. A horse could still be used as a stud even after it is dead.
Celebrity merchandising. Instead of having to give a sperm sample or have eggs harvested, all that's needed is a hair or saliva sample. For the right price you could buy the right to use a celebrities gamete to create your own baby. In essence you would be having their child
Of course that could open up a black market, too. People who go to extremes to acquire samples for their own use; people who acquire illegal samples and sell them (i.e. maid steals Jennifer Lopez's hairbrush and sells the DNA on E-bay); paternity issues (people suing for child support becasue they had so-and-so's love-child when in reallity it was a child created from an illegally produced gamete).
If I can sort things around enough in my mind, what I want the story to focus on is some of the ethics and consequences involved if you could have anyone's baby with relative ease.
I think I'm rambling...
Oh well, now to see if I have a story that will work with this...
