Answer: The Positive vs. Negative system refers to the Rh blood group system. The Rh blood group system currently consists of 50 defined blood group antigens among which the 5 antigens D, C, c, E, and e are the most important ones. When blood is referred to as positive, it contains the D antigen; when it is referred to as negative, it lacks the D antigen. The D antigen is not necessary for survival.
Answer: No, as if Rh positive blood was put into a Rh negative person it would trigger an immune reaction against the transfused blood. However you can put Rh negative blood into a Rh positive person so long as their ABO blood types are appropriatly matched too.
Answer: This not entirely true while an Rh- person can not receive Rh+ blood due to the fact as stated above an Rh+ person can receive Rh- blood because there is no Rh in the blood. This is why O- people are universal donors meaning they are able to give blood to anyone, but can only receive 0- blood.
No. Blood type is determined by a couple of things. The first are the antigens present on the red blood cells. This is where you get A, B, and AB blood types. If you lack either A or B antigens, you have an O blood type. The +/- refers only to the Rhesus factor D, or RhD. It does not refer to other rhesus factors that are not considered in blood type. With this factor, you either have it on your blood cells (+) or you do not (-). It is impossible to have a positive blood type and not have rhesus factor D because that would be a complete contradiction to the naming system.
Answer: Yes a person can have " O " only without being +ve or -ve .. my blood type is O .. >>> Good Question Yes a person can have " O " only without being +ve or -ve .. my blood type is O .. >>> Good Question
Parents have two genes for pos/neg blood type, and only one of them needs to be positive for the parent to have positive blood type. Most positive-blooded people have one positive gene and one negative gene. If both positive parents pass on their negative gene, they can have a child with a negative blood type.
Answer: YES Rh Positive (Rh+) and Negative (Rh-) Blood Types The Rh (+/-) factor is inherited separately from the ABO blood types. Similarly to the masking effect of the O gene in ABO blood types, the Rh negative (Rh-) gene is also masked by the presence of a Rh positive (Rh+) genotype. Therefore, a person may have a Rh + blood type and can still have an Rh - gene (See the chart below). Furthermore, 2 parents with Rh + blood types can have a child with Rh - blood type.Genotype (DNA)Blood Type(+ , -) or (+ , +)Rh +(- , -)Rh -
Answer: Yes. Blood types are only partially dependant on the parents blood type. The parents geneology is more important and only one parent with the recessive negative rh gene can pass it to a child. as for the type (A, B, AB, O) that again is dependant on the genetics of both parents. It is easily possible. If you are in doubt get a DNA test done. There are many hospitals and clinics who will for this for an affordable, if not free, price.
Yes. Regarding blood type, each person has two blood group genes--one from each parent. The blood types sort like this:
For blood type O: O/O
For blood type A: either A/A or A/O
For blood type B: either B/B or B/O
For blood type AB: A/B
Thus two parents who are A/O (and are therefore blood group A) can have a child who is O/O if they both give the O gene, resulting in blood group O.
Regarding Rh type, each parent also give one gene, either Rh - or Rh +. An Rh + person can be either +/+ or +/-: and Rh - person is -/-.
To summarize: a mother who is A/O and Rh +/- (and thus A positive) and a father who is A/O and Rh -/- (and thus A negative) can have a child who is O/O and Rh +/- (and thus O positive).
Answer: O positive has no A antigens or B antigens and so can donate to people with A type, B type and AB type. However they as it is positive it does have the rhaesis antigen and so can only dontate to other positive type people. (A+, B+ and AB+)
