can a child's blood group be O+ if his father has A+ & mother has A- blood group?
439008
YES. Absolutely, despite all the answers you've received to the contrary. \n\nThe way blood groups are named, either your blood contains certain proteins (named A and B) or it doesn't - if you have both you are blood type AB; if you have only A you are A; if you have only B you are, you guessed it, B, and if you have neither you are blood type O.\n\nIf you have a gene for a blood protein, either A or B, you will have that protein in your blood. However, we have two copies of each chromosome, and it is possible that each parent has one copy of the A gene on one chromosome, and doesn't have it on their other chromosome (O). This means they will both be blood type A, since they each have one copy. However, if they have a child who happens to get the O chromosome from each of them, then the child will be blood type O. Mathematically expressed, each parent is AO, and on average their children have a 25% chance of being AA (blood type A and cannot have type O kids), 50% chance of being AO (blood type A but able to have type O kids), and 25% chance of being OO (blood type O).\n\nThis is the whole idea of recessive genes, which also explains why two brown-eyed people can have a blue-eyed baby without any hanky-panky going on.\n\nAs regards the Rhesus factor, i.e. the "+", again that is a recessive characteristic. The child must have received the Rh factor from his father, since his mother is negative. (NOTE that any Rh-negative woman who has an Rh-positive baby should get a shot of something called RhoGam, or WinRho, to prevent problems in future pregnancies.)

yes\n\none parent is blood type A+, and the other is B+.\n\nTherefore, can be represented as AO, and BO.\n\nin this way, it is possible to have an AB, AO, BO, and OO blood type, more commonly known as AB, A, B, and O

It has bee several years since I studied blood banking but I think I remember this.  This is a really rare blood type.  To begin with, blood type is determined by antigens on the surface of red cells.  There are two of these antigens, A and B. a person can have one or the other, both or neither resulting in type A, B, AB or O type blood.  Whatever blood type a person has, They have antibodies against the others except for O since it has no antigen.  The antibodies are what make on blood type incompatible with another.  Type O blood is considered the universal donor because there are no antibodies against type O, except in the case of Bombay blood type.  These people actually do have antibodies against type O blood cells.  The condition is extremely rare and very dangerous for those who have it.

The answer is E. For a child to be AB, neither parent can be O, but can be any other blood type.  Keep in mind that each blood type has 2 alleles. The genotype for a B parent can be BB or BO, for A parent AA or AO, or the parent can also be AB. Different combinations of these can create an AB child, but if you have an O parent, that parent is always OO (because O is recessive if you want to look at it that way), and so the child would be either AO, BO, or OO. There's no other choice with an O parent. An O parent only has an O to give, and the AB child needs to get an A and a B, one from each parent.

Yes, type O can recieve type AB. I am a type O.:O) Any other blood types, more than likely your body will reject it. Along time ago my cousin had a tropical disease called dengue fever(mosquito disease) in tropical countries and she was a type O and the blood bank had little type O blood, so they mixed A and B blood together and it worked. She is now a happy and healthy woman. :O)

Yes.  Your child may be A+, O+, A-, or O-.  The + part of the blood type is dominant to -.  You and your husband would have to each have a + from one parent and a - from the other parent in order for your child to receive 2 - genes and have rh- blood.  Having a different bloodtype than your child can lead to serious complications, especially during the second pregnancy.  If during the birth of your first child, your body is exposed to your baby's blood (and the blood is a different type than your own), you may build up antibodies to your baby's blood.  If your next child has the same bloodtype as your first child, your body may actually attack the baby.  Be sure to talk to your doctor about bloodtype dangers.

im not aware of any diseases associated with blood types A + B. the only issue is if a mom as a non-compatible blood type with her baby, sometimes that can cause a problem but even that is usually not an issue

Firstly, the idea that your blood will never regenerate is false; blood cells have a life span of thirty (30) days, meaning that your body is constantly regenerating blood anyway.  However, if an individual loses a large amount of blood very rapidly, it is crucial that he or she obtain blood from a donor, because blood cannot be regenerated quickly enough to compensate for a large loss.\n\nSecondly, it is not common to get an O- blood type anywhere, as it is a recessive genotype to all the other blood types.\n\nIf your parents are both type O, then you are most definitely type O.  As for being O- as opposed to O+, it is very rare among families comprising mostly of O+ individuals.  (On the other hand, families with O- always have children with O- until another family member with another blood type joins the family).  However, it is possible if and only if a pair in your preceding family (i.e. great grandparents) were carriers of the O- blood type - this is likely, because you ended up with O- blood type.  There are a much greater handful of O+ individuals who bear O- genes than is apparent, but it's certainly possible; therefore, they are able to pass on those O- genes to their offspring.

People have either type antigen A, B, or a combination of both (antigen AB). The ones who lack both are thought has having type O antigen. The way our immunity works is by attacking any thing that it recognizes as "foreign". Any individual with blood with antigen type A will attack others individuals type B and viciversa. Individuals with antigen type AB will receive type A and B blood, because the blood perceives it as it's own ( thus called universal recipient); this means that this patient can receive any type of blood either type A,B, or O. O type of antigen means that the blood lack any type of antigens ( meaning that it lacks of antigen A or B); which means that when this individual donates blood, the other individual does not detect any antigen A or B in the blood; thus there is no reaction to it. Thus an individual with type O is called universal donor, which means it can donate blood to any type A or type B individual. Well that is the basics i hope you find it interesting

The differences in human blood are due to the presence or absence of certain protein molecules called antigens and antibodies. The antigens are located on the surface of the red blood cells and the antibodies are in the blood plasma. Individuals have different types and combinations of these molecules. The blood group you belong to depends on what you have inherited from your parents.\n\nThere are more than 20 genetically determined blood group systems known today, but the AB0 and Rh systems are the most important ones used for blood transfusions. Not all blood groups are compatible with each other. Mixing incompatible blood groups leads to blood clumping or agglutination, which is dangerous for individuals.\n\nNobel Laureate Karl Landsteiner was involved in the discovery of both the AB0 and Rh blood groups.\n\nCheck the full text\n\nhttp://nobelprize.org/medicine/educational/landsteiner/readmore.html

it is very simple \nif ur blood type is o+ than u can receive blood from o+ and o-\nif ur blood type is o- than u can only receive blood from O-

There are some rare factors in human blood, but the major groups are Type A (genes AA or AO), Type B (genes BB or BO), Type O (genes OO), and Type AB (genes AB). The Rh factor is important, also - either + or -.

The women and the man would have a heterozygous geneotype\n\nThe woman's genotype would consist of a gene for B blood and for O blood.\nThe man's genotypes would consist of a gene for A blood and B blood.  \n\nSince O is a ressisve gene, A and B would dominiant the blood type for their children who could have an A, B or AB blood type.  \n\nFollowing a basic 2 x 2 Punnett square, the statistics of a child getting a homozygous B blood type would be 1/4; a AB blood type would be 1/4; for getting a heterzygous A or B blood type with a ressive O gene would be 2/4 or 1/2.

Yes, start with your blood type....for example 0+,\n\nnow check your siblings (brother & sisters)\nnow check your parents....and see who's blood everyone has!\n\nNow check your grandparents, and/or your aunts...if available.\nIt's amazing how many people do not know what their blood type is!

Their children will either be A or B.  One parent will give either an A or a B gene and the other can give only O.  Since O is a recessive gene it will take two of them to make an O child.\nGenotypes:\nParents:  \nAB\nOO\nChildren: \nAO\nBO\n\nIf they have only one child there is a 50% chance of A type and a 50% chance of B type.

The blood group of parents do not determine the sex of the child just the blood group of the child. Both my parents are O+ve, and i have got a brother. Its just the chromosomes X and Y that determines the sex in humans.
