and are co-dominant whereas is recessive to other two.
Thus, if a person with blood group O produces offspring with blood group B then the other parent must contain allele.
The genotype of other person can be , , or .
There is only one condition in which the person can have offspring with blood group O that is, when the other parent is .
In this condition, the probability of an offspring to have blood group O is 50%.
In other conditions, the probability of an offspring to have blood O is 0%.
If am almost 100% sure it is neutrions .
All of them, when a disease infects an object it can last for a long time if not cleaned
