my husband and I are both Rh positive but our daughter is Rh negative. Is it possible that she got that from recessive genes?

She must of if this is the case. I am RH- and both of my parents were A-, and I was told that I am RH- because both my parents had negative blood, so your daughter must have gotten it through one of your DNA structures.

only 3 in 20 people are rhesus negative and i think it may occur spontaneously regardless of parents genes.
How did it affect your pregnancy as I know it can have some effects on the baby doesn't it?

We each and each carry 2 genes that code for Rh factor, getting one from each and each determine. So your mom might have 2 copies - one effective and one unfavorable. effective Rh is dominant over unfavorable, so as a result she has a effective Rh sort even with wearing the unfavorable gene. She surpassed the unfavorable gene to you. Your father might desire to be effective like your mom, and be a provider of the unfavorable gene. Or, he might desire to hold the two copies of the unfavorable Rh gene and he himself could be Rh unfavorable. In the two case you inherited a unfavorable gene from him to boot, imparting you with 2 copies, one from each and each determine, making your Rh unfavorable. Your sister might desire to be Rh effective if she inherited even one effective gene from the two determine.
