Answer: It is possible for two O bloody type to have a child of Blood type B which can be caused by mutation.
Mutation is the changes in genetic content or DNA . Although it is normal for two O blood type parents to have O type child but it is technically possible for O blood type parents to have child of A or B blood type which is due to changes in DNA. Changes in DNA can be caused when sunlight hit our bodies, conversion of food to energy , when our body absorb some chemicals and when our cells try to copy another DNA. The differences between the blood types A, B, and O is very small. This makes it possible for a mother of O blood type produce B egg or a father of O blood type produce B sperm which is caused by mutation.
For a parents with blood type O to have a child with B type blood, the parents blood type O would have to look like B type .
