Negative Rh factor

I have a Negative Rh factor and my husband is positive. I believe my daughter is negative. What are the chances that our other children will be negative? ( A-, O+ and daughter is I think O-?)


Off the topic a bit but anyone know anything about reoccurring leg pains, thought it might be hereditary or something. Thought it was due to lack of Calcium too but doesn't see that way any more I take 3 600mg tablets a day some times a little less maybe one more every now and then.

thanks in  advance.

There are two copies of the gene for Rh negative or positive. Positive (+) is dominant over negative (-), so by the fact that you are negative, we know you are -/-. You only have a - to pass on to your children. Because one daughter is also negative, we know that her father is +/-.  Therefore there is a 50% chance for each child to receive the + gene and be positive.
