Rh+ means a person is positive for the D antigen. Type B has another type of antigen. Antigens are proteins on the surface of blood cells that can cause a response from the immune system. ", yes your father would have to be A+O- as his whole blood type and as the previous person said the Rh factor is recessive. Is there a way to make a baby registry only ship to my house, not to the person purchasing? If a parent has type AB blood, they can not have a child with type O blood. The Tech is a registered 501 (c)(3). This A, B, AB and O doesn't harm your kid. A DNA test is the best way to move forward. Best, @MsGreene Our current understanding of genetics is that it is not possible for one parent to have type A- blood, the other parent to have type A+ blood and their child to have type AB+ blood.

Otherwise, the baby should be at least 2 months old, since a fair amount of blood is needed for the test.

Only 2 out of 1000 men could possibly be the father. Why don't libraries smell like bookstores? My dad and I both did the Ancestry DNA test and he is my biological father. You may develop antibodies to an Rh-positive baby. So this is how an O parent could produce an A child, with a single base change. If a mother is B pos and the father is A pos can the baby be O neg. No there is no possibility of another father. Both parents have to be h carriers, though a parent can be a carrier without actually having Bombay type blood. So, if a mother is AO and the father is a BO, there's a 1/4 chance that the baby will be . I have ab- blood type and my husband has a positive.

This can happen as a lab error, a reporting error, or someone remembering a different type than they were told. my blood type is B- am i going to have a baby ? Sadly, you may never have the answer you’re looking for. .. All i can imagine is either she got my blood type or her dad .. In a situation where the mother knows there is only one possible father of her baby, and the outcome is “not possible” the blood types are likely different than what is thought. Am I a freak of nature? They are considered 99.999% accurate. But they could not both be Rh-, so if one parent was A- or AB- the other would have to be B+ or AB+. You also have the option to opt-out of these cookies. Each person’s blood is one of four major types: A, B, AB, or O. Jamaica. Still have questions? In some places such as Mumbai (which was formerly called Bombay) the occurrences can be as high as 0.01% or 1 in 10,000. is impposible. These are general rules, though, and exceptions apply. This time though, the parent would have to have O-type blood which looked more like B-type than A-type. Here's a sequence of DNA bases from the ABO gene. A brown-haired baby whose parents have red and blonde hair respectively inherited the brown hair from another relative. Along the same lines, it is possible for mutation to account for any blood type in a child or are there limitations on which mutations are possible? My father’s blood group is O+ In fact, you might be able to add back a letter nearby without too much trouble. Let's say there's a man named Bob with one B type and one O type allele.

If so, and if your father has type O+ blood, and your mother has type B+ blood, it’s time for a paternity test. My mother is O- my father was 0+ (there was never any affair or baby-switching at a hospital as I was born at home. For example, two O blood type parents can produce a child with only O blood type. If you have type O blood, each of your parents past an O allele down to you. First off, NO THE BABY AND MOM DO NOT SHARE BLOOD. http://www.expectantmothersguide.com/library/pitts... Should i keep my baby or have an abortion? They are very helpful, and can be reached at 1.800.523.6487 or healthanddna.com. If the father is A+ and the mother is A-B- , can they have a child that’s 0-. Blood type names are a little confusing. They are extremely accurate and considered definitive in determining paternity. If you are AB+ one parent would be type A+, A-, AB+, or AB- and the other parent would be B+, B-, AB+, or AB-. Where would I look to see if maybe I’m AO. — If a person has type O blood, both alleles are O. hello But it requires a different kind of mutation.

In fact the coin could land several times in a row on tails and laters, several times in a row on heads. However, that doesn't mean their blood isn't ever in contact with one another. They can also have children who are B+, A+ or A-. Get your answers by asking now. Get your answers by asking now. More on recombination. It is also now possible to determine the father before a baby is born. — Each parent passes down exactly one allele to each of their children.

The material on this site can not be reproduced, distributed, transmitted, cached or otherwise used, except with prior written permission of Multiply. But remember that every person actually has two different forms of a gene -- one from each parent. The placenta cannot filter out all maternal antibodies or diseases. The amniotic fluid may be obtained by a process called amniocentesis. If there is a question, a DNA paternity test is the only test considered definitive. You will need to wait 3 to 4 long weeks for the results. It can be confusing, but here are the basics: Please let me know if you have any additional questions. Also, be aware, that blood types are often different than what they are thought to be. Two parents with A blood type can produce a child with either A or O blood types. Please keep that in mind when reading my comments and replies.

MY blood types is A+my wife blood types is B- my child blood types is AB+ is it possible ? Does that make sense to you or would you like further explanation? My mother is O+ and my father is A+ does this mean that my father isn't who I thought it was as there has always been doubt surrounding this matter anyway. This means the chance of having different fathers is higher than if you had a rare blood type. The child’s blood type is AB+. In the above statement, “if” is key. Type A is one A and one O (AO) or two As (AA).

If you are AB+ neither biological parent can be O+ or O-. If you have B+ blood and if your son has B- blood, his father could have B+, B-, O+, O-, A+, A-, AB+ or AB- blood. There may be others. The most common (by far) are A, B, and O.

However, it is not uncommon for blood types to be different than they are thought. In fact, a child can get almost any kind of blood type if you consider the effect of mutations. My Bd group is B+ve , My Wife bd group is O +ve , which bd group possible in baby . Mother with AB blood type can either pass the A or B allele to the baby. There is a very rare blood type (0.0004% or about 4 per million in the general population) known as the Bombay Blood type. If a child has type A blood, one of the parents must have type A or type AB blood. Type O blood is no antigen. This is why if you have a baby who is Rh positive and you are Rh negative your next pregnancy will be watched very closely. This procedure is performed no earlier than 13 weeks into the pregnancy.

We call the most common blood types A, B, and O. For more severe cases, the baby may be delivered early or given transfusions while in the mother’s uterus. Bt my blood group is B+ how is it possible Less than 1/4 teaspoon is sufficient for the test.

Is there a drug the girl can take to make the babies come out as Twins? Is that considered correct? My mother is O- and me and my sister are both O+.

Both are called type B blood. When a person has a child, he or she passes one of the alleles down to the child. Did the 49ers swing a local California election? From everything we now know about genetics, that is true.

If they come back the same, still an “impossible blood type” you can have a DNA paternity test run to show the father is the baby’s father. If they still come out the same, consider a DNA paternity test is the only test considered definitive. By the way, these different "forms" of a gene are called alleles. If you are Rh-, your parents could be Rh+ or Rh-. It’s not uncommon for blood types to be different than they are thought. Having a baby is a lifelong responsibility and hopefully an even greater reward — for somebody! — If your child has type A blood, he got an O allele from his father and an A allele from his mother and neither passed on the D antigen.

If one parent has type A blood and the other has type O, each of their children can have type A or O blood, but not type B. It depends on the blood type of the mother and the father. This means you have become sensitized and your antibodies can cross the placenta and attack your baby’s blood. My mother is type O, my father is type B, you’re saying that it’s normal for me to have type O? Therefore they never make a working enzyme. My dad is O+. As I’m sure you’ve read, it is perfectly normal for one parent to be A+, the other to be A- and their child to be A-. So, if a mother is AO and the father is a BO, there's a 1/4 chance that the baby will be. For a child to have type A blood, one of the parents would need to have AB or A blood type. * Each group of three DNA bases tells the cell which kind of protein building block to use. Changing only one base can change the code entirely. Me and My husband are O+ and our son is B+ You are not alone. Thank you so much.

Think of the DNA helix-Both parents have a say in the childs blood type, not just the mother, there are allelles taken from the 9th chromosome of each parent and it is catergorized as A, B, AB or O.
