Question

A different couple has a child with O type blood who has a blood disorder and
needs regular transfusions. The mother is type B, and the father is type A. A
genetic counselor created a punnett square to show them the chance of having
another child with type O blood. The results are shown below:
What is the chance of the couple producing another child with type O blood? __%

Answer 1

Answer:

25%

Explanation:

A simple way to think of the punnett square is to think of it as divided into fourths. Only one of these fourths has o type blood. Therefore, there is only a 1/4 or 25% chance of them having another child with o type blood. Hope this helps :)
