In humans, blood type alleles IA and IB are codominant to each other and each is dominant to i. What is the probability of an offspring with blood type A from a couple of blood types AB and B? Assume that the three blod type alleles occur at equal frequencies in human populations.

a.) ABO blood types are determined by a single gene with 3 alleles. Alleles A (IA) and B (IB) are co-dominant to allele O (i). Cecilia, a woman with blood type A whose father and mother both had blood types AB, marries a man named Joseph. Joseph has blood type B. Joseph’s mother had blood type O. What is Cecilia’s genotype with respect to blood type? b.) ABO blood types are determined by a single gene with 3 alleles. Alleles...

1. In humans the allele for A type (IA) blood and B type blood (IB)show co-dominance, so that a person with both alleles has blood type AB (phenotype). Both A and B alleles are dominate to the allele for O (i). A person with an allele for type A blood and an allele for type o blood marries someone with an allele for type B blood and an allele for type o blood. List the types of offspring they could have and...

ABO blood types are determined by 3 alleles at an autosomal locus: IA and IB are codominant, and iO is recessive. Assuming H-W equilibrium, if the frequency of the iO allele is 0.1 and the frequency of the IAallele is 0.6, predict the frequency of all 4 blood types in the population (type A, type B, type AB, and type O).

In the ABO blood groups, there are A, B, O, and AB blood types. They are due to three alleles, IA, IB, and IO, with IAIA and IAIO having blood group A; with IBIB and IBIO having blood group B; with IAIB having blood group AB; and with IOIO having blood group O. Among many aboriginal American Indian tribes, the allele frequency of IB in the ABO blood groups is extremely low. In one sample of 600 Papago Indians from...

There are three main alleles in the ABO blood group system -
IA, IB, and i. We've talked about the ABO
system in class, you can find a brief explanation below and
here.
The I gene encodes for a glycosyltransferase
that modifies at the H antigen.
The glycosyltransferase encoded by IA adds an 'A'
sugar group to antigen H, the glycosyltransferase encoded by
IB adds a 'B' sugar group and i encodes an inactive
glycosyltransferase that leaves the H antigen...

ABO BLOOD TYPE The ABO blood groups in humans are determined by multiple alleles. A single gene can exist in any of three allelic forms: 14, Bor i. This inheritance of the ABO blood type displays codominance as well as complete dominance. The two codominant genes A and B code for production of antigen A and antigen B on the surface of red blood cells, and are both completely dominant to the recessive allele i. The chart below shows the...

In simple Mendelian inheritance alleles display a simple dominant/recessive relationship. There are many exceptions to Mendelian laws of inheritance. Most genes have more than two allelic forms and do not exhibit simple Mendelian inheritance. The human ABO antigens are an example of a multiple allelic trait. There are three ABO blood group antigens, IA, IB and i. The i allele is recessive to both IA and IB. A person who is homozygous ii has type O blood and does not...

Background for Discussion: Blood type is determined by the "alleles" that are inherited from the parents Alleles are possible types of a particular gene, in this case the blood type gene. There are four main blood types A, B, AB, or O; and three basic type alleles A, B, and O. Children have two alleles, one inherited from each parent. Blood types A and B are called co-dominant alleles, while type O represents the absence of a factor and is...
