What percentage of genes do two animals have to have in common in order to hybridize?

There is no magic number.\n\nIt is not a matter of genetic distance as much as it is number of chromosomes, and other pre- and post-zygotic barriers.\n\nGiven that we are all very genetically close (by the numbers at least) it will be interesting to see what the future brings in the way of hybridization of animals (plants have already been messed with A TON).

I don't think that was a documentary.  \n\nGorillas, chimpanzees and humans may share a common ancestor, but we are far enough apart genetically that interbreeding would no longer be possible.  Each species has a different number of chromosomes in their cells for one thing.\n\nIt would take a lot more manipulation than artificial insemination to get a genetic hybrid of gorilla and human.

Histology is about tissues, I think. Why don't you do a shared DNA percentage study. For instance, our percent shared DNA is exrtremely high with great apes ,of course. So, how would it match other mammals? Or, maybe even non-mammals like fish or something. If you don't like that idea, you could always test for pollutants and toxins in the tissues of various animals.

6. Each hybrid has 3 alleles a dominant and a recessive. Three hybrids...3 X 2 = 6

First thing you have to realise is that all mules are NOT sterile. Most mules certainly are, but there have been numerous authenticated accounts of mules giving birth to perfectly healthy foals.\n\nNext thing to do is to ignore those people saying that it is because they are hybrids or because horses and donkeys are different species. Numerous species are perfectly interfertile despite being far more distantly related than horses and donkeys and having far more widely differing chromosomes numbers.\n\nThirdly ignore those people saying that mules are clones. Mules are the product of sexual reporduction. If they were clones then by definition they would be either entirely horses or entirely donkeys.\n\nAnd finally mules have perfectly functional reproductive organs so that isn't the reaosn.\n\nSo why are mules sterile?\n\nThat’s pretty complicated and to be quite honest we still don’t know the whole story. The basic problem is that after the ancestors of donkeys and horses split the chromosomes of BOTH species fused and then those fused chromosomes re-split. That has led to a situation where the information originally carried on a single chromosome in the ancestral species is now found on 2 different chromosomes in mules and 2 totally unrelated chromosomes in horses.\n\nNormally a developing foal embryo would receive two copies of each piece of genetic information: one from the mother and one from the father. In the case of a mule foal it receives a random number of copies. It will receive three copies of some pieces of information: 2 from the mule parent and one from the horse/donkey parent, or it will receive only a single copy from the horse/donkey parent.\n\nBecause of that mismatch of genetic material the embryo has a hard time developing. Some traits it will lack sufficient information for since it has only half the required genetic information, while other traits will be overdeveloped because there are 3 or more genes where there should be only two. All mules will get pregnant if mated, but the embryo develops for just a few days and then dies because it lacks the correct genetic instruction to develop further.\n\nAs for why some mules, maybe one in a thousand, are fertile, nobody is quite sure.

nope... they have a difference level of chromosomes,\n\n\nthey more than liekly could try.. but the results would be more than likely dead and birth from physical problems such as no lungs, or no heart etc..\n\ndifferent animals have maanged to mate ouside thier chromosome levels, such as the donkey and horse, and the lion and tigers (Ligers).. normally these animals do not last a full age and have birth defects.

because domestic ducks/geese come from three species the muscovy duck, the mallard and the greylag goose. These were domesticated to make all the forms you see today. Canada Geese can hybridize freely with Greylag geese because they are (quite) closely related. These offspring can also reproduce Mallards often mate with farmyard ducks because farmyard ducks are often just funny coloured mallards so no problems there. Muscovy ducks and mallards frequently interbreed making an infertile hybrid or mule duck (which tastes good!). Pintail are able to hybridize with farmyard ducks as they are the same genera as Mallards (anas) but they dont unless they are in collections because they have a choice of mates in the wild. Wood Ducks are in a genera apart from mallards called Aix, which they share with mandarin ducks from china. Due to this they are less likely to mate with mallards but it is possible because most potential hybrids are possible although not always as fertile young. Other birds dont get involved because waterfowl like to keep it in the family :)

No, your trying to splice two different genomes together... Animal and Humans don't share the same genetic code, DNA to do this...\n\nIf you tried it, whom ever volunteered to be transplanted would die. The horse would have died because the brain was disconnected and vital organs stopped when it happened.  \n\nSince our brain is connected to keep the heart pumping, and since the heart of a horse is so different, our brains wouldnt keep it going as thier chambers are more than ours are, or they dont beat the same, plus the various muscles couldnt be grafted to our synapse to control over.\n\nI wish you well..\n\nJesse

Pretty story, but genetically impossible.  Cats and dogs have a common ancestor, sure, but so do cats and people, and dogs and mice, and every single mammal that's around.  Cats and dogs belong to different taxonomical families - they have different chromosome nubers and different genes on different chromosomes that mean that no such thing as pittens or kuppies could be produced.  Yes, horses and donkeys can breed to produce a STERILE offspring - the mule or hinny, but that's because they're extremely closely related members of the equus family with very similar behaviour/courtship.  Cats and dogs aren't even that close.\n\nAnd puppies couldn't be born from implantation in a cat's womb - the DNA would be rejected by the mother as completely foreign.  Its being tried between camelids (alpacas/llamas etc) and an embryo doesn't implant even between these two very closely related species, so there's no way we can implant two such diverse species as a cat and dog, who are as closely related as a human and a lemur, or a horse and a rhinocerous.

Hybrids - usually created in laboratory conditions, but sometimes in a zoo.\nLook up liger or tigon - amazing animals - a mix of tiger and lion

Let B mean the genotype for dominant black fur and b mean the genotype for brown fur. \n\nRecall that when a gene is dominant, it is always expressed when  it is present. When a gene is recessive then it is ONLY expressed  when there is no alternative.\n\na) Pure black mice would have B1B2 and brown mice must be b1b2 because it is a recessive gene. (I've put in the numbers to act as subscripts so it makes more sense.) Crossing these, you would get offspring that inherit one gene from each parent.\nB1b1 ==> black\nB1b2 ==> black\nB2b1 ==> black\nB2b2 ==> black\n\nSo false because all the offspring from pure black and brown rats would be black. \n\nb) True. Pure black mice have BB. As both parents have BB then there's not a chance for bb to occur!\n\nc) False. Brown mice are always bb (recessive) so bb x bb can never result in Bb or BB. So offspring of 2 brown mice are always brown.\n\nd) Heterozygous black mice are Bb. So crossed with brown mouse bb (b1b2):\nBb1 ==> black\nbb1 ==> brown\nBb2 ==> black\nbb2 ==> brown\nSo you get equal numbers of black and brown offspring. True.

Ligers and Tigons are sterile from birth, so there would be no offspring.  However, if one were to unlock the secrets behind genetic recombination, you could sample DNA from both animals and possbly splice a new, third hybrid ... perhaps a Tigron.  Sadly, natural pathways for an enhanced hybrid from these two creatures is impossible.

I think you mean hybridized, or crossed, this is the proper term when different animals are combined.  For instance a horse crossed with a donkey is a mule.\n\nCloning is when organisms share exactly the same genetic material.  Clones are a natural occurrence in the plant kingdom.

A)\n\nThe white mouse shares the phenotype and genotype of parents\n\nMother white mouse: aa\nFather white mouse: aa\nWhite mouse: aa\n\nThe Brown mouse might be 2 things, \neither heterozygous: Aa\nor homozygous dominant: AA\n\n(in these type of exercises, when you mate something with an animal from which you have no info, he's usually homozygous. And if he wasn't the next step would not work.)\n\nTherefore, the mating of the white mouse (aa) with the brown mouse (AA) give only heterozygous (Aa) brown mice.\n\nWhy not B?\nBecause if the white mouse was heterozygous (Bb), that meant that "White" was the dominant gene, and the brown mouse had to be homozygous recessive (bb). But now you can say that they still could have a brown mice offspring, because they both carry a recessive allele (bb). Well, yes, but eventually white mice would appear in the be born (BB, Bb). This way it would never be all brown.\n\nWhy not C?\nBecause all the offspring would then be all white and never brown. It's the inverse of example A).\n\nWhy not D?\nBecause the white mouse is alive and fertile.

Sheep and goats will attempt to mate with each other but this mating usually does not result in offspring.  The outcome, when it does occur, is known as a sheep-goat hybrid.  One example is the so-called "Toast of Botswana"\nThere is also an animal known as a geep.  It is part goat and part sheep but it is produced by artificially combining the embryos of the two animals.  It is not produced naturally.

I do not think you could hybridize a turkey and a chicken. They are too far apart in species variation. A chicken has 78 chromosomes, but I do not know the turkey number. I think we would have seen the hybrid, by now, if it were possible.

our genetic code is 99.999 % similar.\n\nsince human species has not arrived too long (on a geological/whatever scale) the varation of genes between humans is very little.\n\nthere is much more genetic varaibility between chimps, monkeys, cows, rats etc....than between humans.
