I read a report by a woman that claims that when mating with her great danes she would miss her period and then 6 weeks later have a massive one. Her husband was a vet and she claims that he fertilized the great dane eggs and then implanted them into her and she gave birth to five puppies. No way to verify but she claims she has done it more than once.

I'm not buying that ;) Urban myth at best.

I think I read about that one, on the stories and fantasy board here, it is a fantasy for some, but medically impossible

It's completly impossible for reasons already mentioned. Also its incredible sensitive even within simular spieces. You take a seagull from one side of the planet and then another from the other, get them to mate. You find that even though the same spieces or simular, they cannot produce offspring. Also it happens with spieces that are crossed like the donkey-horse cross, aparently they cannot bare offspring and are considered sterile

not exactly, what they did was take a bovine egg, remove the bovine DNA from within the egg and then implanted human DNA, let it grow for 4 days and then destroyed it. It was believed that if implanted into a womens womb, the egg would grow into a live fetus. What isn't known is weither this fetus would be some kind of bovine-human cross. The reasearch into creating such hybrid and simular experiments have since been banned by both Canada and the United States Governments back in Oct 2003.

What you need is some sort of DNA abstraction layer virus to section off the parts of both genomes, match them and then patch any empty sections with inactive filler DNA. No telling how many chromesomes you'd end up with if trying such a hack. Probably have to make it stick to the maximum number of one species or the other.

And designing it to respond to only mammalian DNA and reject random microbe DNA, and solving countless other little problems would likely take lifetimes and produce a huge stack of Nobel prizes, new companies, a few dozen new branches of science and who knows what else.

Even then, in the end, I doubt you'd end up with anything that would work across the entire set of chromesomes. Might be usefull for plant genetics though.

To do it right you'd have to model everything on computer simulations, selectively splice, and/or snag some Nth party DNA block just to get a clean intermediate match.

And the DNA sets would have to be "pre-cleaned" by irradiating clones of candidate cells to make sure they weren't prone to random breaks, mis-splices, etc. The same for any sets of post engineered cells as well.

All of this today is pure theory. Like talking about 16,000 node, 80 Gflop per node, beowolf clusters in an era when they use punched cards and relay logic computers. Give it 50-80 years, then there might be a hint of a possiblity of doing it for real. ;)

As far as I know both Father & Mother would have to be of same Family, such as Equus, Canis etc, which is why Indian elephants can make liittle ones with an African one as they are not of same Family. Yet lone Genus.

its not possible ,but its fun to try.so girls can relax about it and if they were worried they dont need birth control.even if the egg is fertilized and it didnt get expelled it wouldnt develop into something.

It is impopssible, I would say 100% not possible without any alterations. But if a way is found to alter the dna in human sperm I would say it might be possible to achieve this there is a very slim chance.

I would like to ask why would anyone want to do this? It has been a fantasy but other than that I dont see any necessity to do this. Cloning has been researched and to some extent ben successful, we can use cloning to save endangered species, but why create hybrids?
Aren't there enought species on this earth already?
Is it not enough that we just see to that none of the present species go extinct? These are the question one should ask oneself before thinking about impregnating animals.

Making it so two species could freely intermate probably isn't practical for the types of applications people are talking about here.

However, if you identify a biological niche that needs to be filled, you could create a hybrid to fill that. Usually this only applies in plant biology. Animals tend to adapt on their own pretty well without help. So worst case you might have to splice a few segments here or there.

Theres also the issue of vanity hybrids, like finally being able to post engineer mules so they could breed. And tweeking the DNA of other species that due to limited gene sets now have a hard time interbreeding. Such as how coyottes and wolves tend to not intermix easily. If you had a virus that corrected for the problems you might more or less save the wolf population by allowing it to take advantage of the more diverse and populous dog and coyotte populations.

Getting any studys to agree on the last concept there would be probably more difficult that getting a manned mars mission to work. You still have people who will rant, rave, and turn all colors of the rainbow saying that coyottes and dogs/wolves can't interbreed. If you showed them the actual hybrid animal, and the gene chart to go with it they'd probably lose it completely. Doesn't do much immediate good to have all your wildlife biologists in padded cells, but I suppose it would clear out the dead wood for once and for all. ;)

Evilphil,

Genetics and evolution do not work like that. Plants are remarkable in that it is quite easy to insert chromosomes into the species and not destroy it. Thus there are naturally occurring and man made hybrids out there with gargantuan amounts of genes. Animals are far more specific and sensitive to genetic differences. If things don’t line up for meiosis, it just won't work.

You have natural selection backwards... we cannot impose evolution on animals by choosing an ecological niche for them and genetically altering them to fill it. The process you speak of happens in the reverse. An existing environmental pressure acts through time on a population to change the expression of genes as connected with reproductive success. This produces changes within a population and eventually may lead to new species.

you cant get an animal pregnant. wtf

;) Give some ass clown Frankenstien scientist some time and there will be hybraid human and animals. :huh:

Can't happen - and for all the reasons stated above. B)
