In summary, the RH factor is a protein found on the surface of red blood cells that is inherited from parents and can be positive or negative. It can affect genetics when a parent with a negative RH factor has a child with a positive RH factor. It is possible for a child to have a positive RH factor even if both parents are negative, and the chances of this happening are 50%. RH factor genetics can also impact pregnancy, as Rh incompatibility can occur when a woman with a negative RH factor becomes pregnant with a baby who has a positive RH factor. The RH factor itself does not change over time, but a person's blood type can change due to certain medical conditions or procedures.

For a reaction, the blood of the baby and mother must be mixed. If it's not, there's not going to be adverse effects.
 

Related to RH Factor Genetics: O+ve with -ve Parent Possible?

1. What is the RH factor and how does it affect genetics?

The RH factor is a protein found on the surface of red blood cells. It is inherited from parents and can either be positive (+) or negative (-). The Rh factor can play a role in genetics when a parent with a negative RH factor has a child with a positive RH factor.

2. Is it possible for a child to have a positive RH factor if both parents are negative?

Yes, it is possible for a child to have a positive RH factor if both parents are negative. This is because the RH factor is inherited from both parents and can be a combination of the two. A child can inherit a positive RH factor if one parent carries the gene for it, even if they themselves are negative.

3. What are the chances of having a child with a positive RH factor if one parent is positive and the other is negative?

The chances of having a child with a positive RH factor in this scenario is 50%. This is because each parent passes on one copy of their RH factor gene to their child, meaning there is a 50% chance of inheriting the positive RH factor from the positive parent.

4. Can RH factor genetics affect pregnancy?

Yes, RH factor genetics can play a role in pregnancy. If a woman with a negative RH factor becomes pregnant with a baby who has a positive RH factor, it can cause complications if their blood mixes. This is known as Rh incompatibility and can lead to health issues for the baby.

5. Can the RH factor change over time?

No, the RH factor is determined by genetics and does not change over time. However, it is possible for a person's blood type to change due to a bone marrow transplant or certain medical conditions.
