male AA + female OO will produce AO that is A bloods group\nmale AO + feamle OO will produce AO and OO ,,so can be A or O group

O pos, A pos, B pos are the most common. Next is O neg, A neg, B neg. All RH neg blood is considered rare but the most rare are AB pos and AB neg. If you are a female with a negative RH factor and you become pregnant from a man with a positive RH factor, you will need a shot or your body will reject the pregnancy and you could lose the baby. If he is negative also, the baby should be fine. If the female is postive she can carry a baby with negtive blood type just fine. The blood type O pos can go to any POSITIVE blood type, O neg can go to any NEGATIVE blood type. O pos can only receive O pos, and O neg can only receive O neg.

all normal males are XY.  all normal females are XX.  the female always donates 1 X chromosome to the offspring.  the male donates either an X or a Y to the offspring (50% chance of each event).  If the male donates an X, the offspring will be XX and female.  if the male donates a Y, the offspring will be XY and male.

To answer this question you must look at it through a punnet square.\n\nMother- I^A I^B\nFather- I^A I^A OR I^A i  (i = Type O)\n\nThe mother being Type AB defines for us each of the alleles that make up here blood type: I^A and I^B.  \n\nThe father being Type A provides only one clue: that he has at least one A allele.  Because an A allele will mask an O allele, it is impossible to know whether or not he has homozygous for Type A blood (I^A I^A) or if he is heterozygous for Type A blood (I^A i).  Even as a heterozygote, the father will express Type A blood.  \n\nFor this reason you must create two separate Punnet Squares.  In one the father's genotype will be I^A I^A and in the other his genotype will be I^A i.  In both the mother's alleles will remain constant with I^A and I^B.  \n\nYou will realize, however, that because the mother has no Type O allele (i), there is no possibility that any of their offspring will have Type O blood.  This is because Type O blood only appears when both alleles are for Type O (i i).  Since the father has possibly one O allele, and the mother has no O allele, a homozygous genotype for Type O blood cannot happen.\n\nGood luck!

Yes,there should be worried if father is Rh+ and mother is Rh-.This also may not creat problem for thier first child because mother blood has not started  making antigen against Rh+.But after thier after thier first child has been born then, of course, mother has started making antigen.Then thier second child child will die of embryonic erythroblastosis.I think you have understand the process.

As everyone has told you the only type not possible is O\nbecause to get type 0 blood which is recessive you would need a recessive allele from each parent. Obviously if you are AB (which are codominant) you do not have a recessive allele. The child could Inheret either the A alle or the B allele and would end u p with type A, B or AB blood depending upon the allele passed by the other parent.\nI see you also want to know if there are any blood types not possible for the children of a person with O type blood to get. Yes, a person with O type blood cannot end up with a child with AB blood because they have 2 recessive alleles. They could end up with children with A  B or O phenotypes

no doesnt matter as far as blood groups go. AB, B, O whatever theyre all just as good. \n\nhowever, genetic testing to see if people carry a rececive gene that could result in diseases like cystic fibrosis or tay-sachs might be a good idea.... but you could always adopt or hope your kids dont get those diseases, so i wouldnt look to far into it. plus you might scare off your girl if you make her get all kinds of blood tests before you get married

to what? have four children with four different blood types?\n\nYes, theoretically. Depending on the full genotype of the mother and father, but if they are both heterozygous (i.e., if Michelle's genotype is AO, and Mike's genotype is BO), then the possibilities for children include:\nAB\nAO\nOB\nOO\n\nIf they are both homozygous, however (ie, AA and BB), all their children will be AB. \n\nAnd then of course there are various combinations if Michelle is AO and Mike is BB or Michelle is AA while Mike is BO. A punnet square will help you out there.

The Blood types would have to be 50% chance of Oo and 50% chance of Ao. Remember the three possible alleles in blood are A, B and O, out of the three only O is recessive. So in order to be heterozygous A you have to actually be Ao, If the other allele was a B, it would be AB. Because O is recessive, any individual with O blood type is automatically Oo. The punet squar then looks something like the following\n\n______ Oo\nAo___Ao Ao\n_____Oo Oo, \n\nHope that helps

Blood group is highly related to genetics. It is possible to have an O child even if both parents are not O.\n\nIf the parent's are both a heterozygote, then there is 1:3 chance that the child get an O blood group. However, if at least one of the parents are homozygot, then it's impossible.\n\nAbouth the two Rh+ become Rh-. It's also possible, since it's basically the same as the ABO blood group, if the Rh+ parents are heterozygots then it's possible to have a child of Rh-. \n\nSo:   \nBO +- >< BO +-\ncan have a \nOO --\nchild.

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-

Blood type has to do with chemical markers on your cells called antigens. People with type A blood have A antigens, and people with type O blood have no antigens. A person has two genes controlling blood type, one from each parent. Both your parents have the genotype AO. Because they have the gene for A, they produce the antigen for that blood type. However, you inherited the recessive gene from both your mother and your father (genotype OO) and therefore have no antigen-producing genes. This makes you type O.  \n\nTherefore, if your spouse also has type O blood, then any chidren you produce would also have to be type O. The person above me is either mistaken about her parents' bloodtypes or the identity of her parents.\n\nThe RH factor (+/-) works in a similar fashion.

YES,  yes,  yes.\n\nThe father  CAN  be blood type "O" and the mother\ncan be blood type AB. The baby will be A or B.\nSince the father thought his type was O, something is amiss.

According to the information given, it is not possible for the A negative child to be your child. Bummer. Sorry. You better re-test to make sure though.\n\nIf both parents are type O, their children must be type O as well.

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.

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

25% chance of being O\n75% chance of being A\nonly if both parents are heterozygous\n\neven if one is homozygous no chance of getting "O"
