Blood type phenotypes refer to the observable characteristics of an individual's blood, primarily determined by the presence or absence of specific antigens on the surface of red blood cells. The main blood type phenotypes are A, B, AB, and O, which correspond to the presence of A antigens, B antigens, both A and B antigens, or neither (respectively). Additionally, each blood type can be classified as Rh-positive or Rh-negative based on the presence of the Rh factor. This results in eight possible blood type phenotypes: A+, A-, B+, B-, AB+, AB-, O+, and O-.

What is Phenotype O?
Phenotype O refers to individuals who have type O blood. This blood type lacks the A and B antigens on the surface of red blood cells. People with blood type O can only receive blood from other type O donors but can donate to individuals with any blood type.
Is it possible for a with a blood type alleles Ia and Ib to have blood type a?
In the perfect world, no. IA and IB are codominant so both alleles are represented in the person's phenotype. Blood type A can only be represented by itself in a phenotype if the person's genotype is either IA IA or IA i.(The result of a DNA mutation may be able to create a phenotype of blood type A out of a (purebred) cross (of blood type A and B).No. IA and IB are both codominant . Blood type A can only be represented by itself in a phenotype if the person's genotype is IAIA or IAi. Blood type B can only be represented by itseft in a phenotype if the person's genotype is IBIB or IBi. If the phenotype (blood type) is AB the genotype is IAIB.
What phenotype is produced by BB blood type?
The BB blood type produces the phenotype associated with type B blood. Individuals with this genotype have B antigens on the surface of their red blood cells and do not produce anti-B antibodies. Consequently, they can receive blood from type B and type O donors but cannot receive type A or AB blood.
How are Genotype phenotype different?
Phenotypes are the traits expressed by the genotype. So, for blood type, a person can have A and i alleles (genotype). However, in the phenotype, since i is recessive, only the A will be expressed, and the person will have an A blood type.
If the father blood type is B and the mother blood type is B what type of blood will the baby have?
the baby can have several types depending on the parents phenotypes:1.phenotype- (BO)X(BO)the child can be 75% type B and 15% type O.2.phenotype-(BB)X(BO)the child can be 100% typeB.3.phenotype (BB)X(BB)the child will be 100% type B.
Can a father with type B pos blood and a mother with type a pos blood produce a child with type O pos blood?
Yes. The genotypes of the father could be BO or BB (Phenotype = B) The genotype of the mother is OO(Phenotype = O) Mating these genotypes will produce either OO (Phenotype O) or BO (Phenotype B) In short, children from these parents are B or O The Rhesus(D) positive was inherited from the father.
In humans blood type inheritance is an example of what?
Human blood type inheritance is an example of codominance, where both alleles for blood type (A and B) are expressed in the phenotype of individuals with the AB blood type.
WHAT IS THE PHENOTYPE OF A2B POS BLOOD?
The phenotype of A2B positive blood refers to a specific blood type characterized by the presence of A and B antigens on the surface of red blood cells, along with the Rh factor being positive. Individuals with this phenotype possess A antigens (A2 variant) and B antigens, making their blood type A2B+. This classification is important for blood transfusions and compatibility, as it determines the presence of specific antibodies in the plasma.
What blood type would a baby have if both parents have blood type O positive?
The baby would have blood type O positive. A child can only inherit blood type O from parents who each have at least one O allele. And since O is recessive, both parents must have two O alleles to have blood type O.
If a man with blood type A and a women with blood type B produce an offspring what might be the offspring's blood type?
Depending on their actual genotypes and which of those genes the offspring receive, their offspring might have AB, A, B, or O blood type. For the man to have a phenotype blood type A he might have either genotype AA or Ao. For the woman to have a phenotype blood type B she might have either genotype BB or Bo.
A parent with type O blood marries a type AB what would be their phenotypes?
Their children's phenotype could be either A or B.
What is expressed when both alleles for a gene are equally expressed as in human blood type?
This is called co-dominance. This is when 2 or more alleles are expressed at the same time. In other words they both affect the phenotype. In the example of human blood ABO type we have an allele for A = IA, B= Ib O=iIAIb = AB blood typeIbIb = B blood typeIai = AIaIa = A bloody typeIbi = B blood typeii = O blood type
