Can two negative parents give birth to rhesus?

Can two negative parents give birth to rhesus?

No, because to be rh negative, one must have TWO rh negative alleles. The rh factor is recessive. If both parents are rh negative, they must have ONLY rh negative alleles. Therefore they do not have any positive alleles to pass on to their children.

Can you be Rh negative if both parents are Rh positive?

The answer is “Yes”. Just like two brown-eyed parents can have a blue eyed child because the rh negative gene just like the blue-eyed gene is recessive. Just like two blue-eyed parents cannot have a brown-eyed child, two REAL rh negative parents can never have an rh positive child.

When does a child get a rhesus-negative blood type?

A child with Rhesus-negative blood — more commonly called Rh-negative blood — lacks the Rh-factor, a protein located on the surface of red blood cells, according to the American Pregnancy Association. People with this protein have Rh-positive blood, while those without it have Rh-negative blood. But having Rh-negative blood is not a disorder.

Do you inherit the Rhesus factor from your parents?

We inherit the rhesus factor from our parents. In the UK, around 85 per cent of the population have RhD-positive blood. Most of us are RhD-positive because we each inherit two copies of the rhesus gene, one from each parent. These genes are either positive or negative. The positive gene is dominant and always wins out.

Can a person be rhesus positive without a Rheus negative gene?

Without a Rhesus positive gene to dominate the pair of genese you got, you are Rhesus negative. I am the same. The reason this occurs is that both of your parents carried only a single gene for Rhesus Positive, and the opposite, carried the ability to pass on Rhesus negative.

Can a brown eyed parent have a Rh positive child?

Just like two brown-eyed parents can have a blue eyed child because the rh negative gene just like the blue-eyed gene is recessive. Just like two blue-eyed parents cannot have a brown-eyed child, two REAL rh negative parents can never have an rh positive child.
