Blood type o recessive

Common Questions and Answers about Blood type o recessive

blood

Avatar n tn Type O blood is recessive so, to my limited understanding, two type O parents each have O-O genotype and will almost always have a type O child, barring a mutation of course. So, assuming no initial error in blood typing was made with any of the parties, with a mutation it is possible, but the mutation is not likely. There are genetic tests available for maternity/paternity that are more in depth than blood typing.
Avatar n tn This means that a child with type O blood could have parents with type A, type B, or type O blood (but not with type AB). Conversely, if two parents both have type O blood, all their children will have type O blood. Another medically important blood type is described in the Rh system. These genes were first discovered in the rhesus monkey, hence the designation Rh.
Avatar n tn Hello cdc29, Just reading your question with regards to blood type. If the father is O pos and the the mother is A pos you can NOT produce an offspring that is B neg. Here is why, we will deal with the blood groups and leave out the Rh factor for simplicity (will explain that after).
Avatar f tn 9% probability of paternity/maternity (depending on the type of samples used).
287578 tn?1198553444 Type A is dominant, Type O is recessive. In otherwords your parents could both carry the gene for O, but the A gene they carry overrides it. You just got the O gene from both of them and not the A. It works like this, imagine your mom's genes across the top, and your dad's down the side. They each give you only one. Each child your parents have have the same chance of inheriting one of each of the following combinations...remember one from each parent equals 2 genes for you.
5889951 tn?1380319647 I was discussing with my sons father who is o negative blood type and I am o negative blood type would my son be o negative as well? If anyone has any info they could share with me I would be very appreciative.
Avatar n tn So if you are type A, for example, you could be AA or AO (you get one gene from each parent). If you're type B, you could be BB or BO. O is recessive though, so if you are type O, you can only be OO. So if a child is type A, with mother type O (OO), then the child must be AO, meaning he got the O from mom and the A from dad. That means dad could be AA, AO or AB, and still pass on the A allele... i.e., dad's type would have to be A or AB...
Avatar n tn Then we look at the amount of population with Type O blood type. Now Type O is recessive to Type A, Type B, and Type AB blood types therefore the chances of another male having type O blood type in the population is not very good chances.
Avatar n tn My fiance just got blood typed as LAN blood type after not knowing his blood type for 23 years, I am O neg. What complications could we have with conceiving and pregnancy?
Avatar f tn I just recently asked what was my blood type because my mom told me I was o-negative. Well I found out that I am but I never received a Rhogam shot. My doctor has never even discussed it with me. Is this a big issue? Will this cause any complications? Has anyone else dealt with this????
1225198 tn?1336791830 My mom is O- and dad is AB+. ANYONE can take O- blood, but - can't take + blood. This makes O- blood like gold, and O+ is pretty important too. You should dontate blood more often! But even in the situation of one partner with + and the other with -, it won't PREVENT pregnancy, it would only make keeping the pregnancy difficult, if not impossible. My mom had 2 miscarrages before finding out the problem. She sucessfully had 5 children with help once she knew she had - blood. Hope that helps.
Avatar n tn Obviously you both have a dominant O blood type but you might also have a recessive A blood type. This would explain how the child got the A blood type. One recessive A from mom and one recessive from dad. The positive and negative factor (RH factor) is a protein marker and is not connected with the blood type. Most likely the baby got recessive A's from both of you then a negative from the person who had the negative RH factor.
Avatar n tn If the baby's blood type is O, then the mother or the father would have to have O blood, that is the way it was explained to me. With my daughter I had O+, Ava has A+...we do not know what her Daddy's blood type is, but the hospital explained that her Daddy could only have A, or AB in order for Ava to receive the A type. I did not question paternity but I wanted to have Ava's blood type in her records at home. I assumed she would have my O type, I was a little bummed when they said A+.
Avatar m tn My oldest daughter Amira has an O+ blood type. My new born has a B+ blood type. Their mother has an O- blood type.Is it possible for both kids to be mine?
Avatar n tn I'm not sure why you're asking, but I'll also add that someone with A or B type can have a recessive gene for O type, so that they can parent a child with O blood. Hope this helps.
Avatar f tn No and yes. Type O blood type is caused by the recessive gene of O,O alleles. That means that the only allele a person with type O blood can pass down is O. Someone with B type blood must have the genotype B,O-so one that person's parents must have to have a B blood type or an A,B blood type in order to pass that down. HOWEVER there is a VERY rare condition that I studied while I was taking genetics. I just can't remember what it's called.
Avatar n tn Is that true--- I have type AB+ blood n the father has/had type O? I have 2 children-- they both have type AB+ blood type. I am confused???? n startled now, by that????
Avatar f tn It is not unusual for blood type A parents to have blood type O children, since O is a recessive trait. Your son having blood type O does NOT indicate non-paternity. In other words, you and your wife, though both blood type A, a dominant trait, may both carry a gene for O blood type. You can find a good explanation of genetic inheritance patterns at the following site: http://anthro.palomar.edu/blood/ABO_system.htm Hope that helps.
Avatar f tn If a question of paternity is riding on it, it would not be too cautious for both parents to get their blood type checked with new tests. Then have the child's blood tested (again) as well. This is to prevent jumping to conclusions. A lot of grief could be prevented if the couple were to find out their blood types weren't what they thought. For example, my husband's blood type is A, why does he know this? Because he thinks it was on his Army dogtag 30 years ago. Mine is O.
Avatar n tn I have already had an H Pylori blood test to rule out an ulcer, an ultrasound and an MRI which were unremarkable. I am getting very tired of this!
Avatar n tn You just have to separate the letter from the + or -. O is the recessive letter type, so if you are O, then your gene is OO. If you are A, you can be AA, AB, or AO. If you are B, you can be BB, or BO. If you are +, you can be ++, or +-. If you are -, you can only be --. Therefore O+, and O+ could only equal O+, or O- (that would be assuming you carry the recessive - trait). To get an A+ baby, you would have to have one parent that is A, and the same parent or the other parent would have to be +.
Avatar n tn They are both O- blood types. I understand that two O-'s can only produce an O-. I am not O-. I understand that a mother contributes her type and her RH factor (+/-) and the father can give his type or his recessive type and his RH factor or his recessive RH factor. So the theory is that if the baby is O-, it could be mine or his, but if the baby is anything else, it is definetely mine.

Avatar f tn I'd like to start a relationship with my distant blood-relative. My grandfather's father and his mother's father were brothers. Which type of cousins or relatives exacly are we then? And is it dangerous to get married and have children?
Avatar f tn Looked at another way, where parents are first cousins, there is about a 95 chance out of 100 (95%) that they will have a baby unaffected by a condition due to the parents' faulty genes o The chances of having a baby with a problem would be higher, and parents more likely to share the same faulty gene copy, if their parents and/or grandparents are also close blood relatives * In most families where the parents are close blood relatives, there will be no history of a specific condi
Avatar n tn why didn't you know your blood type before?? just curious, i thought all adults knew their blood type, i concider that pretty important information, especially since i'm O.
Avatar m tn I am blood type O and he is OB recessive. I am aware that my blood type is universal so it should be ok for him to receive my liver. His doctor said that most of his liver has been damaged, but seeing he seems to be getting healthy does he have to undergo a transplant? How successful is live liver donor transplant? What should I do to prepare myself for this operation? Are there any hospitals or institutions that do liver cloning?
