can you breed a big dog to a horse?

Answer 1

ummmm.....no. But I once dated a guy that was half pig :)

Answer 2

DNA structure is essentially the same for all organisms, although the details of the genetic code do differ. Genes from one organism can be modified and introduced into another organism to produce a transgenic animal. First a transgene is created. This is done by identifying the desired section of DNA is identified and addind with "extra" DNA that allows the new gene to express correctly and at the proper time. The "extra" DNA is the promoter sequence, and a poly-A termination sequence which must be added to signal that the end of the gene sequence has been reached.

The newly created transgene may then be microinjected into eggs harvested from super-ovulated animals and fertilised in vitro. Two hundred to three hundred copies of the transgene are microinjected into the recently fertilised eggs. These are then implanted into surrogate mothers. Only a small proportion of the animals born are transgenic (i.e. can pass the gene on from one generation to the next) and only a proportion of those express the gene well. These successful animals are called founder animals. Genes can only be added, not deleted by this method.

They are then mated with non-transgenic animals to produce a second generation of offspring that are heterozygous for the gene. The second generation heterozygous offspring are then mated with each other to produce a percentage of offspring which are homozygous for the desired gene. The resulting homozygous third generation offspring will then have a stable form of the gene available whenever they mate with other homozygous offspring.

Another method would be to microinject embryonic stem cells from one species into the blastocyst stage of the embryo from the second species. The resulting fetus will be chimera.

As in the first technique further selective breeding is then required for homozygous expression.

Nexia is a company that specializes in transgenic animals. Its most successful animal to date is a species of African pygmy goat that produces the proteins for spider silk in its milk. The proteins from them milk can be spun into fibers that have ballistic properties.

Another very beneficial transgenic application is tissue engineering such as growing human ears in mice. The resultant ear can be used to replace an ear damaged in an accident or for a congenital defect where the ear is missing.

Answer 3

Aside from the fact that they're different species, which has already been thoroughly explained, you'd be hard-pressed to find a dog or horse that would be attracted to each other. A mare would kick away any dog that managed to somehow get high enough to get up there (and a dog's penis is miniscule compared to a stallion's, anyway), and a female dog, assuming the stallion would get that low to have sex with something, would just run away. But, again, they're not going to be attracted to each other (unless you have some very weird pets).

Answer 4

No you cannot breed different animals not in the same gene pool, you can for instance breed a horse and a donkey but then you get only a mule which is sterile and cannot reproduce.

Answer 5

No.....you can't breed a dog to a horse.Their geneic make up is very different. Breed dogs with dogs and horses to horses!

Answer 6

Ask our local government. Military genetics testing department.

Answer 7

no they are not close enough genetically.
That is why you can cross breed horses and donkeys and lions and tigers.....yet they produce offspring who have no reproductive abilities.

Answer 8

No, they're totally different species.

Answer 9

eew! maybe like a great dayne or something.. how would they reach it? but thats really wierd!

Answer 10

u need to get out more please read a book or take up jogging
do not corupt the morals of innocence
