What blood types would your parents have to be to have a child with A positive blood type?
Discounting rare but possible mutations the following holds true. Parents blood groups A and A, A and B, A and O, B and B, B and O, O and O can produce type O blood in their children. The rhesus factor (Rhesus positive/rhesus negative) depends on the rhesus pairing in the parents as follows: Father rhesus positive, mother rhesus positive or rhesus negative = rhesus positive or rhesus negative Father rhesus negative, mother rhesus positive = rhesus positive or rhesus negative Father rhesus negative, mother rhesus negative = rhesus negative Example: A rhesus positive father and rhesus positive mother of blood type A and O respectively could produce an O positive child, as could a rhesus positive father and rhesus negative mother both of blood group O.

How many blood types are there how blood type is inherited?
To the second question the answer, in short, is YES; To answer the first question, there are four logical blood types: A, B, AB, and O. Then there is the Rhesus factor: either positive or negative. So there are actually eight types of blood a human can have: one of the above types with a negative Rhesus factor or with a positive Rhesus factor. Rhesus factor is a factor which compares human blood to a Rhesus monkey's blood. A negative result means your blood is not comparable to a Rhesus monkey. Blood types are inherited from your parents. If one parent has type A+, and the other has a B-, your blood type can either come out as A, + or -, or B, + or -, or the rare AB, + or - but not O. While type O negative is the universal donor, type AB positive is a universal recipient.
Why is blood group O not always a universal donor?
The classic blood typing into groups A, B, AB or O is only one way to divide up the population. Also whether you are rhesus negative or positive can play a big part. If you are type O but rhesus positive, your blood cannot be given to someone type O but rhesus negative or their immune system will react to the rhesus part of the donated blood.

What blood type will the child be with parents blood type O positive father and mother O positive?
The baby can only be an O Blood Group as both parents can only be carrying 'O' type genes. The baby would have a 75% chance of being an O positive and a 25% chance of being an O negative. This is because the mother can only pass on a Rhesus negative gene but the father might either have two Rhesus positive genes or one Rhesus positive and one Rhesus negative. If the first is true the child will only be O positive, if the second is true it could be O positive or O negative depending on which gene the father passes.

Are Spina Bifida and rhesus negative blood connected?
No, they are not connected, although both conditions could occur in the same child. Any two conditions can occur in one child, but that does not necessarily mean the conditions are related. Rhesus negative blood depends on the blood type of the parents. Spina Bifida is a spinal condition, which has nothing to do with blood type.
Is it possible for a child to have o positive blood when the father has b positive and the mother has b negative?
Yes. Each person has two genes to make up their blood group and rhesus group, one from each parent. For blood groups, groups A and B are dominant over O, and for rhesus groups positive is dominant over negative. If you have one of each, your type will be whichever the dominant one is. Firstly looking at the blood group - an O group child can be born to group B parents if both the mother's and father's blood group genotype is BO. The child has a 25% chance of being BB (group B), 50% chance of being BO (group B) and 25% chance of being OO (group O). Looking at the rhesus group - mother's genotype must be Neg/Neg, father could be pos/pos, in which case the child will always be rhesus positive, or pos/neg where the child has a 50% chance of being rhesus positive, and 50% chance of being rhesus negative.
My parents are a positive how are you rhesus negative?
In genetics, you have to distinguish between two categories of features: features of the phenotype and features of the genotype. The phenotype are all the features your body actually has, such as your eye color, your hair color, your blood group and your rhesus factor. The genotype is the information actually contained on your DNA. While you may have blue eyes, your DNA might actually contain data for brown eyes that is simply not translated and therefore doesn't show. (More in detail, you have two chromosomes for each task, i.e. information for everything in your body exists in two slightly different versions in every one of your cells, but only one of the versions is actually used.) In the process of meiosis, the chromosome set is halved so that every sperm and every egg cell only contain one chromosome for each task. When they come together, the sets combine and make a whole (doubled) set again. Now if both your parents were rhesus positive but you're negative, that simply means both your parents have on one chromosome the information for rhesus negative, and by chance a sperm and an egg cell both with rhesus negative met.
Can a child be O negative if both parents are O positive and three of the grandparents are O positive and one is B negative?
It is possible as the Rhesus factor is a dominant trait. So, even if the parents have only one allele for the factor, there is a 1/4th chance that the child could get neither allele from the parents and end up as O negative.
What blood factors make a b negative?
RH factor in blood types stands for "Rhesus Factor". Blood tests were performed on Rhesus monkeys and the Rh+ and Rh- factors were isolated. An antigen found in the red blood cells of most people: those who have Rh factor are said to be Rh positive (Rh+), while those who do not are Rh negative (Rh-). What about the meaning of RHD- Rh blood group, D antigen . The rhesus complex is not just one antigen, but several, when someone is told to be Rh+, it usually refers to the D antigen (one of the components of the Rh complex), because it's the most common, and the easiest to identify, however it's not the only one.
Can two parents with negative blood type have a baby with O positive blood type?
Yes parents who are both B blood group can have a child with O negative. This is because B blood group only requires one parent gene to be B to have B blood group - they may also have one O gene. People have two blood group genes, one from both parents. B gene is "dominant" as is A gene. O gene is "recessive". AB blood group means a person has one A gene and one B gene B blood group means a person has either one B gene and one O gene or two B genes A blood group means that a person has either one A gene and one O gene or two A genes O blood group means that a person has two O genes Rhesus positive or negative is similar - positive is dominant and therefore a person with one positive gene and one negative will be rhesus positive. A person who is rhesus negative has both negative genes, and received one negative gene from both parents, both who may be rhesus positive ( with one positive and one negative gene each). Importance of O negative blood - O negative blood group is called the "universal donor" because the blood is least likely to cause transfusion reactions so is safest to use in an emergency before blood groups can be identified and matched. If both parents are A+ can a child be B+?
