Rh Positive Mother Rh Negative Father
Not if first preg.: Rh sensitization usually occurs after delivery of a child who is Rh +, and mom is -. Fetal blood may mix with maternal blood. If not given Rhogam (antibodies against Rh + blood) her immune system will be sensitized to Rh+. Fathers who are Rh+ may be carriers of Rh -, with 50% chance of an Rh - infant with no risk. Even if sensitized, fetal therapy can allow survival of an Rh + baby. ...Read more

Usually: It is commonplace for a pregnant mom in that situation to receive rhogam around 28 wks of gestation and again after birth if the kid is rh+. If the kid turns out to be rh- the 2nd dose is omitted. ...Read more
Only if you are Rh+: Rh positive mothers having rh+ babies-no problem! Rh negative mothers with a rh+ baby especially the first and subsequent pregnancies will require Rhogam injection post delivery to prevent future rh disease issues and baby losses. ...Read more
Rh negative and not sure who the baby's father is. Odd are Rh positive like 85% of the population, right?
Correct: Because you are rh negative, you should be offered Rhogam at 28 weeks and after delivery if the baby is rh positive. Also, there are some other situations where Rhogam may be given, but they are less common. ...Read more

My mother is a+rh positive and so is my dad, my blood type is a-rh negative. How is this possible?
My father is A+, my mother is A-. My Mother is rh negative. I'm trying to make sense of things. I'm A- rh negative. Is this possible?
Yes: That sounds fine. In such a scenario, if you had many siblings, some would be Rh positive and some would be Rh negative. ...Read more
Yes: The rh factor is determined from both parents. Each parent contributes one half of the infant's rh type. Each parent has 2 rh genes. So, if each parent (of the child in question) has a "split" rh: (-)/ (+), i.e. Half negative and half positive--they are reported as "positive". Yet if each parent contributes the "blank" or rh negative portion to baby then he is (-)/ (-) or rh negative! ...Read more
Antibody formation: At the first transfusion, nothing happens, but the person generally makes antibodies to Rh antigen and may have a transfusion reaction at the subsequent transfusion with Rh positive blood. If it is a woman of reproductive age and the baby is Rh positive, the baby may get hemolysis. ...Read more
Blood group antigen:
Rhesus (rh) blood group is one of the more than 20 different blood group systems. One of the markers in rh system is "d" that is used in the terminology you inquired about. If rh d is present the person is rh positive and vice versa. See this site for more info (more than one needs)

Many ways: If this is first pregnancy for Mom, less likely to cause miscarriage from Rh issue. If second or more pregnancies, increases possibility of hydrops fetalis from Rh negative Mom and Rh positive baby. Best way to follow is with serial ultrasounds to judge level of anemia and need for fetal transfusion or early delivey. Good luck. ...Read more
Is it possible for 2 parents to be rh-positive and have a rh-negative child? I know my grandmother was rh-negative, but no one else since, for 3 generations now. I am o positive, but my child was rh-negative. We so desperatly want and or need answers. We
based on mendelian genetics, it is possible for two rh+ parents to have an rh- child. Each one of us has two alleles (one from our mom and one from our dad). Homozygosity means that both genes are the same. Example: "t" = tall and little "t" = short. Homozygosity means you as a person has tt (two tall genes). If you were a heterozygote, you would have one tall gene (t) and one short gene (t), i.e., tt, but you would still be tall because the big t is dominant. It is the same concept with rh. You are a heterozygote for rh meaning you test positive but you have one recessive gene which was passed on to your child. This also means that your husband is a heterozygote and he passed his recessive gene to your child so that your child has two recessive genes and is rh negative. Your grandmother mated with an rh positive male (your grandfather) and your parent is a heterozygote which explains why you are also a heterozygote with the blood type o positive. I hope that answers your question. ...Read more
Rh positive: Each person carries two alleles, if either is positive, the person if Rh positive. Among Asians and American Indians, Rh negative alleles are quite uncommon. Among the Basque, a majority of the alleles are Rh-negative and thus a larger minority of people are Rh-negative. Among folks of European ancestry, around one person in 6 has two Rh-negative alleles. ...Read more
Rh exposure: Exposure to Rh positive blood can produce an immune response and the development of antibodies directed at the Rh antigen. In non-pregnant individuals, this causes no significant problem, aside from the potential hemolytic reaction if they receive Rh-positive blood again. But blood banks test for this and should easily avoid it. In a woman who may become pregnant, harm to the baby can result. ...Read more
If you have a Rh negative father and Rh positive mother, is the unborn child at risk? Can it complicate the pregnancy?
If mothers blood group is rhs O neg and baby blood group is O positive what would the fathers blood group be?
Father's blood type: Father is O positive. In the A-B-O nomenclature, A and B and dominant and Rh + is dominant over Rh -. That means that the baby had to get an O allele from both mother and father and at least one Rh + allele from a parent. Mom is OO neg neg and that means that the father has to be OO pos neg or OO pos pos. Either way, the father is phenotypically O pos. ...Read more

Seldom a problem: With regular prenatal care this combination is seldom a problem.

Yes: Ab blood type you have one gene for a and a gene for b. If both parents give the b gene the child will be b type blood. Rh + can be one or both genes rh+ or one - and one +. Rh- you both genes are rh-. So if baby got rh+ form one parent and rh- from the other the baby would be rh+. ...Read more
Can a O negative blood group father and a A positive mother have healthy children. Does the mother require any shots during pregnancy?
The A positive mother does not require Rhogam. OB guidelines in most countries are adequate to provide for a healthy pregnancy and delivery. Requirements for anti D immunoglobulin admin. Is for the rhesus negative mother given before exposure to RhD antigen. Incompatibility in the ABO system can be very easily managed by the OB and the peds/neonatologist. Take care.

Not possible: It is possible for the child to be rH negative if both parents are hybrid rH positive (one positive and one negative rH gene), but if they are both type O can only have type O children. Either one of them is not the biologic parent, or someone's blood typing is a mistake. Someone had to give that B gene. ...Read more

Father has o positive blood mother has o positive rhfactor blood child was born with b positive blood how can this be?
Blood type genetics: Abo blood type refers to antigens present on red blood cells. From each parent you inherit an a antigen, a b antigen, or no antigen. People inheriting an a and an a are type a. Inheriting an a from one parent and nothing from the other is also type a. Inheriting an a and a b creates type ab. People who are type o have no antigens. If each parent is type o, the children must be type o. ...Read more
