When there is DNA shape mutation, one of the main things that could happend in the change of shape of the proteins, this creates a different pattern to arrange the nucleotids in the nuclei of the cells
If a person has blood type B, that means you can only donate blood to blood types such as AB or B
If a person has O, that means it can donate blood to all blood types
If its A, they can donate blood to blood types of AB and A
If its AB it can donate to blood types of A, B, and AB
