Do animals have blood groups/types like humans?

In man blood group is applied to single factor. This factor is agglutinogen and is also called antigen. It is found on the surface of red blood corpuscles. \n\nAccordingly a person with `A' antigen is designated as a person with A-group, with `B' antigen as B-group, with both A and B antigens as AB-blood group and a person without any antigens is designated as O-blood group. \n\nIn the case of animals blood group is applied to combinations of blood factors. So it is preferable to call it as blood group systems rather then blood groups. Each system has many factors, which are together called blood group factors. \n\nDr. J. Moustgaard, of the Royal Veterinary & Agricultural College, Copenhagen has identified in cattle ten group systems namely A,B,C,FV,J,L,M,SU, Z and R'S'. Except J and L, all the other group systems have more than one group factor. For example the group factors of the group system A are designated as A{-1}, A{-2}, D, H, Z'. \n\nThe grouping factors are particular serum proteins. Acquiring of each protein is an inherited character. So examination of blood sample from within a breed might eventually prove a very useful means of selection. It might also indicate what mating could be expected to result in infertility. \n\nThe B-group system only has greater number of grouping factors. It has nearly 27 group factors, which are called phenogroups. Some of these are unique to particular breeds. \n\nThey are particularly valuable in determining incorrectly stated parentage. In dogs serum major groups have been recognised in the USA and they are referred to as A to G. \n\nIn veterinary practice blood transfusion is used in cases of haemorrhage and shock and to a lesser extent as part of the treatment of certain infectious diseases. \n\nIn cattle the donor and recipient are usually in the same herd. This fact lessens the risk of introducing infection and incompatibility does not arise. \n\nBut normal antibodies against the blood group factor-J are sometimes found in cattle. Thus if the donor's blood is J-positive and the recipient's blood contains normal antibody called anti-J the so-called transfusion reaction might be expected immediately following blood transfusion. These reactions are dyspnoea, muscular twisting, increased salivation and circulatory disturbances. \n\nHowever, if an animal has been exposed to repeated blood transfusions, a different situation will arise. The animal will now have formed antibodies against the blood group antigens it does not have itself. It is therefore by no means unlikely that the blood of donor and the recipient are incompatible. \n\nIf this is so, transfusion will set off strong transfusion reactions. Such reaction can occur on the second or on subsequent blood transfusion\n\nI hope this helps!

Pigs and humans: no.\nChimps and humans: maybe.\n\nHonestly, the scientific jury is still out on whether or not humans are able to crossbreed with apes.  Rumours have cropped up within the scientific community for years, but no definitive cases have presented themselves.  Check out the link below for some interesting reading on the topic.

To my knowledge, nobody is sure what purpose blood groups serve.  It's possible that there is no purpose, it could simply be something that happened because there is no reason for it to not happen.  It's not like blood transfusions happened occasionally to our ancient ancestors, there just isn't that much reason to get rid of them.\n\nHowever, there are some possible explanations.  The one that I seem to hear most often is that they serve a purpose in the immune system.  Look at it this way, if all human blood cells had the same kinds of coatings, parasites could copy those coatings and the immune system wouldn't be able to tell them apart from good blood cells.  By having LOTS of different blood types, a species of parasite can't look like "human blood cell" because "human blood cell" doesn't have a single look.  If the parasite starts to look like an O, it will be spotted as foreign in an A, B or AB person.  If it starts to look A then O, B, and AB immune systems spot it as foreign.\n\nIt's a great story, but a bit difficult to find support for it.  It's not like we can run an experiment where we isolate a population of A+ people and keep any other blood types out, keep them infected with malaria and see if the malaria starts to develop type A chemicals on it's surface!  I mean, we could, but I hope people would object!\n\nAnimals do have blood groups.  In particular, chimpanzees and the great apes have the same blood groups we do as I recall.

i think its because of a mutation in humans, and the mutations caused different blood groups to emerge.

There used to be more than one species of humans but they died out. Technically there are animals that are our species like chimps, but are not humans. Some researches even believe we should be part of the same genus as well. All dogs are one species just different breeds like we have different races.  There are probably so many species of frogs because they can all cohabitate on the earth without interfering with each other and killing each other off.

Hi there,\n\nI'm afraid you need to be more specific in you question. There are many varieties (breeds) in dogs. Each breed has a different scientific name. The scientific name consists of two parts- Zenus and Species. A family of animals like dogs belong to the same Zenus but are of different species. Carollus Linnaeus introduced this type of classification for the first time.\nAs we all know, the scientific name of human beings is Homo Sapein.\nThe scientific name of neem is Azadirachta Indica.\nThe scientific name of Indian tiger is Panthera Tigris.\nThe scientific name of Indian gerbil is Tatera Indica.\n\nrule wid style n luv@vinny

This is a point that has been taken up by those in scientific and academic circles.\n\nSo, no, you aren't the only one.\n\nNot long before I was born, it was assumed that Black blood types must be different than Whites, and Blacks who wanted to donate blood were rejected.\n\nTurns out there's no relation between blood type and race.\n\nThere have been people arguing that the whole concept of race is bogus.\n\nA few weeks ago, I caught part of a really interesting documentary on PBS of a genetics expert who was following out the migrations of humans.\n\nTurns out, everyone in Europe, most of East Asia (northern, primarily) and the Americas are related, and descended from the same small group of people -- who had first migrated to the middle of Eurasia, then some traveled west to Europe, and a very few to the Americas.\n\nThe differences that have sprung up since the separation of people into the "races" are as nothing compared to our shared traits.\n\nAnd no one is "pure" as there has been mixing ever since.\n\nNo, you're both in good company and on solid ground in finding the concept bogus.

I don't think blood type has anything to do with it.  The best diet includes vegetables, whole grains and milk products.

Rh + is dominant, - is recessive; the A blood type can be either homozygous or heterozygous (its multiple allelles), so babies could be O+ or O-, A+ or A-.

Different blood types are formed with evolution:\n\nEvolutionary biologists theorize that the IA allele evolved earliest, followed by O (by the deletion of a single nucleotide, shifting the reading frame) and then IB. This chronology accounts for the percentage of people worldwide with each blood type. It is consistent with the accepted patterns of early population movements and varying prevalent blood types in different parts of the world: for instance, B is very common in populations of Asian descent, but rare in ones of Western European descent.)\n\nAs for other mammals:\n\nThe ABO system is the most important blood type system in humans. The associated anti-A antibodies and anti-B antibodies are usually powerful IgM antibodies. ABO IgM antibodies are produced in the first years of life by sensitization to environmental substances. ABO blood types are also present in other apes such as chimpanzees, bonobos and gorillas.

A "dot" and a "rag". \nNo, seriously, in most cases animals need to be of the same species (not "family" as a previous answer stated) to be able to produce offspring. However some species of the same genus can mate with each other and produce offspring, such as horses and donkeys, lions and tigers, some smaller cat species, dogs and wolves etc. Mostly the interspecies breed is infertile. This possibility is probably not as unnatural as one think but might rather point out that our (scientists') definition of a species as the basic classification unit of life, still contains elements of artificiality.\nYour mentioned species are not known to interbreed, though.

Humans are in the:\n\nDomain:  Eukarya\nKingdom: Animalia\nPhylum: Chordata\nSubphylum: Vertebrata\nClass: Mammalia\nOrder: Primate\nFamily: Hominidae\nGenus: Homo\nSpecies: Homo sapiens\nSubspecies:  Homo sapiens sapiens\n\nHumans are further broken down into races based on physical characteristics such as hair type and color, skin color, features, etc.

It's a genetic variation like eye colour or skin tone.  \nSome specific diseases do not affect certain blood types and thus it seems like differnt blood types have evolved to combat these diseases.\n\n(I am A positive by the way)

http://gslc.genetics.utah.edu/units/basics/blood/types.cfm\n this explains both questions. at the bottom of the page there is a link to "what is a blood transfusion" it tells you how it works too.

monkeys have....dnt they?Rhesus positiv and negative ....blood group typing came frm that only i believe

Yes...however, the human race is one of the few species on the planet that kills one another for conflict not just for survival. In most cases when animals confront eachother it is very rare that one of the animals is killed, let alone seriously injured.

The main blood types are A, AB, B, and O.  These blood types are fromed due to a specific type of protein found on the red blood cells.  A type blood has A protein, while B has B protein.  O does not contain any protein so the O stands for zero.  AB contains both A and B proteins.  Along with this there is the Rh positive and negative type.  This is independent of the ABO grouping so  you can have all the ABO types plus the positives and negatives as well.  So far ther are 8 distinct types.  Along with this there is a M and N type.  This is more subtle and it is usually not tested for. So now we have 16 different types possible.
