My son asked me why he has Type O+ blood and his sister and I have A+ blood. I did not have an answer. Can you shed some light?

Hi @usnret

That is a great question! A child's blood type is dependent on both the mother's and the father's blood types. If your son takes a look at this chart created by the American Red Cross, he will see that since his father has type A blood, his mother's blood type has to be either A, B, or O for him to have type O blood and his sister to have type A blood. For more information about blood and blood types, you can check out the American Red Cross' website here: https://www.redcrossblood.org/donate-blood/blood-types.html.

Thank you for your question!
