How to determine the blood type of future child: tips for young parents

Scientists suggest that expectant parents can predict their child's blood type if they know their own. Sometimes it comes as a surprise when a child is born with a different blood type than the father and mother. Understanding the principles of inheritance will help you understand this issue. This was reported by SSPDaily.

One of the most common principles is Mendel's Law, which explains how blood types change and which blood type parents can pass on to their child. While the tables and recommendations give a general idea, let's look at a few examples that demonstrate possible combinations of blood types.

- If both parents have the type O blood:

When asked what blood type the child will have, medical professionals will say with certainty that the child will also have type O blood.

- If one of the parents has type O blood and the other has type A blood:

In this case, the chances are divided in half. The child can inherit both blood types.

- If one parent has type O blood and the other has type B blood:

The child will inherit either type O or B blood.

- If one parent has type O blood and the other has type AB blood:

This situation may bring a surprise. The child may have a completely different blood type, A or B.

- If both parents have blood type A:

The child may inherit blood type O or A.

- If one parent has blood type A and the other has blood type B:

The possibilities are expanding, and the child can have O, A, B or even AB.

- If one parent has blood type A and the other has blood type AB:

The child will have one of three groups: A, B or AB.

- If both parents have blood type B:

The child will either inherit their blood type or be born with blood type O.

- If one parent has blood type B and the other has blood type AB:

The child can be born with blood type A, B or AB.

- If both parents have blood type B:

There is no guarantee that the child will be born with the same blood type. Possible options are A, B or AB.

To fully understand all the nuances associated with blood type inheritance, you should consult a specialist. Feel free to seek expert advice and ask medical professionals any questions you may have.

Understanding the Rh factor:

When looking at the Rh factor, it is important to distinguish between the positive (+) and negative (-) Rh factor. This factor is determined by the presence or absence of the D antigen.

If a person has the D antigen in their blood, they will have a positive Rh factor. Conversely, if the antigen is absent, the Rh factor is negative.

A positive Rh factor is common, almost all people have it. However, approximately 15% of the world's population has a negative Rh factor in blood tests.

If both parents have a negative Rh factor, their child will also have a negative Rh factor. In all other cases, both a positive and negative Rh factor is possible.
