Why does the baby have only two alleles if the inheritance of blood type is controlled by three alleles?
Everyone only has two alleles for blood type. The parents each pass one down to the child.
What four human groups are controlled by three alleles instead of two?
blood
Is the three alleles of the single gene that controls blood type is said to be what alleles?
multiple alleles
Is ABO blood group determined by multiple alleles?
* Type A alleles could be : IAIA or IAi* Type B alleles could be : IBIB or IBi* Type AB alleles : IAIB* Type O alleles : ii
How do co-dominant alleles work?
Co-dominant alleles are both expressed, because both are translated into RNA. One of the best examples of co-dominance is human A/B blood type. The thing that differentiates A and B blood types is the antigens found on the surface of the blood cells. A person with two alleles for A-type antigens will have only A-type antigens, and a person with two B-type alleles will have only B-type antigens. However, a person with one A-type allele and one B-type allele will have blood type AB. A third allele, O-type, has no antigens on the surface of blood cells, and so is only "expressed" in the phenotype if a person has two O-type alleles (and therefore no antigens on their blood cells.)
What is the blood type in humans controlled by?
Blood types are controlled by multiple alleles.
What trait is controlled by a gene with multi alleles?
The ABO blood groups in humans are controlled by multiple alleles.
Blood type in humans is controlled by which alleles?
Human blood type is determined by codominant alleles.
Why is blood type controlled by multiple alleles?
Yes.
The ABO blood types are controlled by?
ABO blood types are controlled by codominance and multiple alleles.
Why does the baby have only two alleles if the inheritance of blood type is controlled by three alleles?
Everyone only has two alleles for blood type. The parents each pass one down to the child.
What four human groups are controlled by three alleles instead of two?
blood
Blood types in humans are an example of traits controlled by?
Multiple alleles
Blood type in humans is determined by a single gene that has multiple alleles?
Each person has two alleles for their blood type, one dominant and one recessive. Except for type AB blood where the alleles are co-dominant. The allele for O blood is always recessive when paired with either an A or B allele.
How blood type is inherit?
Blood type is controlled by multiple alleles. Blood type is inherited by three alleles, one A, one B, and an O, which is recessive Ex. A= IAIA IAi B= IBIB or IBi AB= IAIB O=ii
When more than two different alleles control a trait?
The presence of more than two alleles that control a trait is called multiple allele. An example of this is the group gene of ABO blood that has three alleles.
What is a trait controlled by a single gene that has two alleles?
widows peaks,straight hair,colored hair
