Both of my parents have rhD positive blood. I came out with rhD negative blood. How?

Question

Mum: O+
Dad: B+
Me: O-

In: 673

Answer 1

Obviously a nurse lied to me. I have O+ blood. My husband had A- blood. My daughter has A+ blood. They told me the child always has the ‘reverse’ (plus or minus) of the letter-type of the father. Clearly reading these answers, this is not so at all!
