Possible Blood Groups of the Progeny

There are four possible blood groups of the progeny that can result from the marriage between a woman with blood group O and a man with AB group. These blood groups are:

1. A group
2. B group
3. AB group
4. O group

Alleles Involved in the Progeny

The alleles involved in the progeny are A, B, and O. The woman has two O alleles, while the man has one A allele and one B allele. When the two alleles combine, they can produce four possible blood groups as mentioned above.

Explanation

Blood groups are determined by the presence or absence of certain antigens on the surface of red blood cells. These antigens are controlled by genes that are inherited from parents. There are four main blood groups: A, B, AB, and O. These blood groups are determined by the presence or absence of two antigens, A and B, on the surface of red blood cells.

The A and B antigens are controlled by two different alleles, A and B, which are codominant. This means that if a person inherits one A allele and one B allele, they will have both A and B antigens on their red blood cells, resulting in the AB blood group.

The O allele is recessive, which means that a person must inherit two O alleles to have the O blood group. If a person inherits one O allele and one A or B allele, they will have the A or B blood group, respectively.

In the case of the woman with blood group O and the man with AB group, the woman has two O alleles, while the man has one A allele and one B allele. When the two alleles combine, they can produce four possible blood groups as mentioned above.

Conclusion

In conclusion, the possible blood groups of the progeny when a woman with blood group O marries a man with AB group are A, B, AB, and O. The alleles involved in the progeny are A, B, and O, which determine the presence or absence of antigens on the surface of red blood cells. The inheritance of blood groups follows a simple Mendelian pattern, which is useful in predicting the blood group of offspring.
