A man having blood group O marries a woman having blood group B and they have a child. What will be the blood group of the child ?

Question

Answer

$ Condition 1st when both are homozygous --------
then 100% blood group of the progeny will be B.....

$ Condition 2nd when male is homozygous nd female is hetrozygous------
then 50% chance is of blood group B nd 50% is of blood group O.....

Answer

1st condition,if father & mother both r homozygous, their offspring's blood group must be b blood group 100%

2nd condition, if father homozygous but mother heterozygous then their progeny will be 50% b blood group and 50% o blood group

Answer

50-50 Percent chances to have B or O BLOOD GROUP OF THE CHILD

Answer

The ABO Blood Group System

The ABO blood group system is one of the most well-known and widely used blood typing systems. It classifies blood into four main groups: A, B, AB, and O. The blood type is determined by the presence or absence of specific antigens on the surface of red blood cells.

Blood Group O

Blood group O individuals have red blood cells that do not have A or B antigens. They have both anti-A and anti-B antibodies in their plasma. People with blood group O are considered universal donors as their blood can be transfused to individuals of any ABO blood group.

Blood Group B

Blood group B individuals have B antigens on the surface of their red blood cells and anti-A antibodies in their plasma. They can donate blood to individuals with blood groups B and AB.

Child's Blood Group

When a man with blood group O and a woman with blood group B have a child, there are several possibilities for the child's blood group. The child can inherit either blood group O or B from the parents, as those are the only two possibilities based on their genotypes.

Possible Genotypes

1. Father (O) x Mother (B):
- Father's genotype: OO
- Mother's genotype: BB
- Possible genotypes for the child: BO or BO

2. Father (O) x Mother (B):
- Father's genotype: OO
- Mother's genotype: BO
- Possible genotypes for the child: BO or OO

Child's Blood Group Possibilities

Based on the possible genotypes, the child's blood group can be either B or O. If the child inherits the B allele from the mother and the O allele from the father, the blood group will be B. If the child inherits two O alleles, one from each parent, the blood group will be O.

Conclusion

In conclusion, the child of a man with blood group O and a woman with blood group B can have either blood group B or O. The specific blood group will depend on the genotypes inherited from the parents.

Answer

It will depend if mother have o as a recessive trait than following are the chances that  child will have ...1. OO  means blood group O 2.BO than B will be the blood group bcoz B is dominant trait.
