OMG I read it and all they did was insert another egg's mitochondria into an egg? That is NOT even genetic modification. Not as the term is properly used.

Much hoopla about nothing.

No, we're nowhere near that. Because of DNA methylation, a form of epigenetics, a viable fetus cannot result from an egg injected with genetic material from two women or two men. One set of chromosomes needs to be from a sperm, the other needs to be from an egg. Taking random chromosomes from different people and creating an egg in which 1/3 of the chromosomes come from 3 different parents would result in some chromosomes having both copies coming from either a man or a woman, which would not be a viable pregnancy.

Doesn't this kind of thing happen allot in the animal Kingdom where animals may have multiple mates?

Oh, that's it?

Umm, no matter how many mates a female has had, every egg will always only be fertilized with one sperm, so no.

very interesting

Ok I see. For example, it's been my understanding that a cat for example can have a litter with multiple mates but each individual kitten could never possibly share dna by two male cats.

I wonder if there'll be a way for gays to have a baby that looks like them both in the future.

Was this to correct a prior abnormality? Like, I wonder if they did chromosomal pre-implantation genetic diagnosis on the candidates first.

I'm still a wee bit reserved about this.

Quite possibly. We just have some things to figure out first. As far as I know, the only thing stopping it is DNA methylation patterns, if we can figure out a way to precisely manipulate those, then theoretically we could suck the DNA out of an egg cell and inject it with the DNA from 2 sperm, one of which had its methylation altered, and voila.

Messing with nature.

I thought they already did this with two females and bone marrow or something
