Rh blood types) Both my wife and I are Rh positive, but our son is Rh negative. Is this possible?

The absence of D results in a gene called ‘d’. Genes Rh Type DD, Dd Positive dd Negative In your family, the genes of both you and your wife must be Dd. Your son must have inherited the d gene from each of you in order to be type Rh negative.
