kaheart [24]

There is 50% chance of the child to be Rh-positive.

<h3>What is Rh factor?</h3>

Some red blood cells have a protein called a Rh factor. Person with this protein are called Rh-positive while those who don't have are called Rh-negative.

<h3>What will be the blood factor of the child?</h3>

When a Rh negative mother and Rh positive father have a child, the child has 50% chance of being Rh-positive. The child may receive the Rh factor from its father.

<h3>What is Rh incompatibility?</h3>

Your Rh factor blood type often doesn't pose a problem. Being Rh-negative during pregnancy, however, can cause issues if your unborn child is Rh-positive. When your blood and that of your child combine, your body will begin to produce antibodies that could harm your child's red blood cells. Your baby can experience other issues, such anemia, as a result of this.
