Weird Thoughts...?

Question

So I was browsing questions and I found this one...
"How can a woman with a lesbian partner become pregnant?
We are seeking for a medical advice on how a woman would become pregnant with a lesbian partner by combining their DNAs. "

Everybody said it wasn't possible, BUT, what if Jane has Lucy's fertilized egg implanted into her body & she carries the egg, kinda like a surrogate mother thing. Would the baby be a blood relative to both? Would the baby have both the mommie's DNA's? I feel like I'm asking "where do babies come from again" LoL.

I was just wondering, wasn't sure, thanks to the informative answers. And blah to the rude ones.

Answer 1

The baby would still only have Lucy's DNA. A surrogate mother does not pass on her own genetics just because she's serving as a host to the fetus. There is no way to have a baby with both women's DNA involved.

Answer 2

There was a scientist in Italy that did something like what the question is asking about. I remembered reading something about it a long time ago but had to search it out and I quote from the Straight Dope: "Soupart used a special process involving a virus to fuse two unfertilized mouse eggs, resulting in a single cell that subsequently began dividing as if it were an ordinary fertilized egg. Soupart stopped his experiment once the embryo (if that's what it was) got to the 64-cell stage, but it's possible the thing could have been implanted in a mommy mouse's womb, so that today we'd have some little rodent waltzing around with two mothers and no father. " I also thought I had heard of similar such things but was not able to track them down.

So I would say that it is possible in theory but to get a lot of men doctors interested in working out the details would probaby be a waste of time. But I would bet that a method could be worked out if people would actually do the research. Incidentally the child, if such were done, would be female since the necessary chromosome to be male comes from the man.

There is another interesting phenomena that is very rare in nature: the chimera. It is where a woman can be her own twin (I read that there are only 30 or so known cases of this happening). A woman has two eggs each of which gets fertilized but somehow the eggs fuse together and produce one baby that carries two different DNAs (read the source to find out about a specific case - I had just read an article on a woman in taiwan who is like this at about the same time I read your question). Now eggs can be fertilized in the lab but I have no idea if you could take one egg from each woman, fertilize them and then artifically join them together. It is done naturally so I would think this could probably be done.

But just carrying an egg would not have both women's DNA. It would only have the DNA of the woman the egg came from.

Answer 3

It is theoretically possible, through genetic engineering, to combine the two half-copies of DNA from any two gametes to form a new, whole copy. Once this new combined copy is formed, it could be reinserted into a viable egg cell nucleus, and develop as any "normal" IVF embry would.

To my knowledge, no researcher has ever successfully carried out this process on a mammal, but it could happen at some point in the future.

Interestingly enough, this process could also permit two men to become father/mothers, they would just also need an egg donor and a surrogate mother. Potentially involving up to 4 people directly as "parents."

Answer 4

The above answer is correct. However, the child's immune system would be more likely to recognize Jane's body as "self" rather than Lucy's. Thus, although there wouldn't be any of Jane's DNA in the child, there would be an immune memory. I'd have to check on blood groups, though--if Lucy's blood type and the father's are not compatible with Jane, that might be a problem.

Answer 5

Ummmm..... where is the sperm needed to fertilize the egg going to come from? And the answer is no - the baby will not inherit the DNA characteristics of the surrogate mother. Only the DNA donated by the sperm and egg donors will be combined - it doesn't matter who carries the baby, their DNA wil not be present in the child.

Answer 6

Lol no it would have the DNA of the mother that donated the egg. A lot of couples do this to feel like they both parented the baby, but biologically it's impossible.

Answer 7

it wouldn't work because its both female chromosomes the cant really combine if it did work something would be wrong with the baby
