What Will My Baby’s Blood Type Be?
For example, if the mother is O- and the father is A +, they think their baby’s blood type will be either O + or A-.
The truth is that blood types are a little more complex than this. It is quite normal for the baby not to share the same blood type as his parents. The law of genetics does not operate mechanically.
Different variables play into the transfer of blood types and Rh. These variables need to be studied in order so that one can more accurately determine what blood type the baby will get.
General aspects
Blood types depend on genetic factors that are hereditary. Traits from both parents will intervene when it comes to shaping the baby’s blood type.
There are dominant and recessive genes. Dominant genes are those that carry the greatest weight. They have a better chance of intruding or manifesting themselves.
According to the blood types, “A” and “B” are the dominant genes. “O” is known as the recessive gene.
Each blood group has different characteristics. Their red blood cells and plasma are different from each other. It gives rise to four blood groups: A, B, O and AB.
Blood types
Every human being has dominant and recessive genes. Depending on blood types, the following combinations are possible:
- Someone in the AB group has one A gene and another B gene.
- A person in group A can be either AA or AO. The dominant A gene predominates.
- If a person is in group B, they can be either BB or BO. The dominant B gene predominates.
- People who are in group O have two O genes.
The combination of the parents’ dominant and recessive genes is what determines a baby’s blood type. There are 16 possible combinations. They are as follows:
IF THE FATHER IS IN GROUP O:
* If the mother is in group A: the child will be group A or group O
* If the mother is in group B: the child will be group B or group O
* If tomorrow is in group AB: the child will be group A or group B.
* If the mother is in group O: the child will become group O
IF THE DANGER IS IN GROUP A:
* If the mother is in group A: the child will become group A or group O
* When the mother is group B: the child will be group O, A, B or AB
* If the mother is in group AB: the child will stay in group A, B or AB
* When the mother is in group O: the child will become group A or group O
IF THE DANGER IS IN GROUP B:
* When the mother is in group A: the child will become group O, A, B or AB
* If the mother is in group B: the child will be group B or group O
* When the mother is in group AB: the child will stay in group A, B or AB
* If the mother is in group O: the child will stay in group B or group O
WHEN THE FATHER IS IN GRUPPE AB:
* If the mother is in group A: the child will become group A, B or AB
* When the mother is in group B: the child will become group A, B or AB
* If the mother is in group AB: the child will become group A, B or AB
* When the mother is in group O: the child will become group A or group B.
The Rh factor according to your baby’s blood type
Blood sometimes contains an antigen, and other times it does not. If it has an antigen, it is Rh-positive. If it does not have an antigen, it is Rh-negative.
As with blood types, Rh is determined by inherited genes. Rh-positive is dominant, while Rh-negative is recessive.
There are opportunities for inheritance of Rh. They are as follows:
IF THE MOTHER IS Rh-:
* If danger is Rh-: the child will be Rh-
* When the father is Rh + (++): the child will become Rh +
* If the danger is Rh + (+ -): the child will be Rh + or Rh-
WHEN THE MOTHER IS Rh + (++):
* If the father is Rh-: the child will be Rh + or Rh-
* When the father is Rh + (++): the child will become Rh +
* If the danger is Rh + (+ -): the child will be Rh + or Rh-
WHEN THE MOTHER IS Rh + (+ -):
* If the father is Rh-: the child will be Rh + or Rh-
* When the father is Rh + (++): the child will become Rh +
* If the danger is Rh + (+ -): the child will be Rh + or Rh-
