Can a child born with rh negative blood type be the offspring of an o positive father?
It depends on the genotype of the Rh+ parent. If that person is heterozygous, then yes there is a 50% chance of an Rh- baby.Father's Group (negative)Mother's Group (positive heterozygous)Rh +Rh -Rh -Rh +, Rh -Rh -, Rh -Rh -Rh +, Rh -Rh - Rh -http://www.bloodbook.com/inherited.htmlIf the positive parent is homozygous, the baby will be positive:Father's Group (negative)Mother's Group (positive homozygous)Rh +Rh +Rh -Rh +, Rh -Rh +, Rh -Rh -Rh +, Rh -Rh + Rh -
Is the phenotype which determine RH?
Genotype determines the rh phenotype. The two alleles for rh factor are rh+ (rh positive) and rh- (rh negative). The rh+ allele is dominant.
You have type O plus why does your father have O negative?
there is no problem with that, your Rh+ comes from your mother :) ur father genotype is Rh-Rh- your mother should be Rh+Rh+ or Rh+Rh- so you took one Rh- from your father and one Rh+ from your mother the result will be Rh+Rh- and because the +ve propriety is more dominant your blood type will be +ve even if you have the mix of Rh+Rh-
Can an Rh positive mother and Rh positive father produce an Rh positive baby?
It MAY be possible but more information is needed about the father. If he is Rh positive then he can be Rh+Rh- or Rh+Rh+.If the Rh positive father has one Rh+ and one Rh- allele, then 50% of his children will get Rh+ from him (and Rh- from the mother) to be Rh positive, and 50% will get Rh- from him (and Rh- from the mother) to be Rh negative.So if father is Rh+Rh- and mother is Rh-Rh-:50% children Rh+Rh- (positive - may cause problems if it is the second child)50% children Rh-Rh- (negative - will be no problems with a Rh- mother)BUT if the Rh positive father is Rh+Rh+ then all of his children with a Rh+ from him and Rh- from the mother. In this case all children will be Rh positive.So if the father is Rh+Rh+ and the mother is Rh-Rh-:100% children Rh+Rh- (positive - may cause problems if it is the second child)Hope this is helpful.
Is it more common to be Rh- or Rh plus?
Rh positive is more common than Rh negative. Approximately 85% of the population is Rh positive.
What color is the tube that blood is drawn for a ABO and Rh factor test?
red top
Why would you use the amnicentesis test?
Amniocentesis is used for diagnosing foetal infections, Rh incompatibility, and chromosomal abnormalties and neural tube defects of the foetus
Why no positive control is used in rh blood group test?
No positive control is used in the Rh blood group test because it tests the presence or absence of A and/or B antigens.
Father has b positive and mother has a negative what will baby have?
The only way to tell is to have a blood test done, it is possible to guess but the only way to be exactly sure is with a blood test. It all depends on Antigens and Antibodies on the blood cells themselves.
What causes the production of Rh antibodies?
Exposure to the Rh (or D) antigen. Most common in mothers who are Rh- who have a child that is Rh+. The mothers immune system will produce Rh antibodies and the blood cells of the NEXT Rh+ baby could be attacked during birth. Rh- mothers are given Rhogam to prevent this from happening. I know this is more than you asked for but every test question dealing with Rh asks something about this it is commonly called hemolytic disease of the newborn

If you have Rh negative blood type do you need to get TB testing?
Whether you have Rh Negative blood or Rh Positive blood has nothing to do with getting a TB test. TB testing should be done at least once a year which will show whether or not you have been exposed to Tuberculosis.
What is d test?
D test is basically a serological test used to detect weak antigens (D antigen of Rh system) to prevent any transfusion mediated reaction in the recipient.
If a father has O negative blood and the mother is a positive what would the child be?
Father is Rh-Rh-Positive blood type has two options so mother could be Rh+Rh+ or Rh+Rh- and so :Rh-Rh- X Rh+Rh+all kids will be positivethe second option isRh-Rh- X Rh+Rh-50% of the kids will be negativethe other 50% will be positive.

Monther is A positive and father is is B negative what make a child ab negative possible?
There are two genes that controll the traits. Since Rh+ is a dominant character, it could be expresssed even in the hterzygous condition. But Rh- could be expressed in the homozygous recessive conditions also. The father is Rh+ that means he could be either Rh+Rh+ or he could be Rh+Rh- and the mother is Rh-Rh-. The father should be Rh+Rh- type. So the gametes formed are of type Rh+and Rh-. When the Rh- gamete of male combine with the of Rh- female gamete the offspring is Rh-, with genotype Rh-Rh-.
