Surrogate mothers

Idk if this is bait or not but I'll still go for it. It's impossible in the first place , even if they had sex in the normal way. It's the chromosome number that differs from animal to animal. So , first of all the zygote won't bond with the squamous part of the uterus ( that's happening once a month , ask ur mom if she's not at menopause ).

Conclusion : Won't work because genetics.

Maybe. Here's something to read.

Or are you saying that an already formed egg could grow in another animal's tummy. Well , I don't think so , because the environment of a dogs uterus differs and the egg will suffer genetic changes that will harm it and will cause abortion. That's totally my opinion ,if you find something legit , pls post.

Are you stupid, anon?
Do you not know what surrogate means?

After you first jumped to conclusions and didn't read OP's (faggot) question.

>you blind cunt
Pot meet kettle

>>2287258
Suppose I have a zygote from my pot, can I grow a new plant in my kettle?

>>2287258
Well, I guess you wasn't that blind. Then why the 1st post , anon. Y so mean?

I only skimmed it, but from what I read it doesn't work for two reasons.
In species not closely related, the embryo fails to attach to the host uterus properly.
In closely related species, development is normal for a time, but eventually the host's immune system recognizes the embryo as foreign material and attacks it.

Success was better when chimeras were created where the portion of the embryo that attaches to the uterus was swapped out for cells from the host.

If you transfer a fertilized human egg to a cow the baby will be born with the ability to talk to animals. This was covered in the documentary Beastmaster.

It would only work if the animals were close enough genetically. I remember a thing on the BBC where a zoo implanted a fertilised egg of a African black-footed cat into a domestic cat and it gave birth successfully. I imagine the failure rate is pretty high though so it's not really a viable solution for endangered species.

One more wiki-degree shitter here, how about this?

https://en.wikipedia.org/wiki/Rh_disease

Mothers have a chance to loose their own pregnancy just because the mother is Rh- and the fetus is Rh+. That is just like 50 different blood proteins, and this results in weak to dead babies.

Dude, that can happen to an egg and a same-species mother. Rh is a total different thing and it happens rarely.

Imo , it's impossible. The amniotic liquid of an animal is different from animal to animal and a dog can't carry a cat egg or a cow can't carry a dog egg. The genetic conformation is different from species to species and mutates the egg which results in the abortion of the fetus (if it only had the possibility to grow)

And it doesn't really solve any of the problems associated with low genetic diversity anyways.
