Why it’s important to know your genotype and Blood Group before marriage

 Falling in love is a beautiful thing and wanting to grow old with your partner is the prayer of all would be couples. But many a times people disregard the most important factor that determine the sustainability of the relationship especially when has to affect to the children to be had by the two of them.
Many families have given birth to children and the children die in their face.

It’s no longer new that couples are advised to know their Genotype and Blood group before getting married, some churches and Mosque have gone further by conducting the test for couples before they join the couple in Holy Matrimony.

Genotype and Blood Group compatibility with your partner is one of the most important factors of long-term happiness in your marriage; it helps you raise healthy children, and saves you a lot of stress in the happy marriage you dream of with your partner.

What is Genotype?

Genotype is the genetic makeup of an individual with reference to a trait or multiple traits. They are the collection of genes passed from parents to the children. Children born of a parent will have different genotype. Exceptions are seen in cases of twins or multiple births that are fertilized from the same egg.

There are four genotypes in humans - AA, AS, SS and AC.  AC genotype is not so common and popular unlike the other three. SS and AC are the abnormal genotypes or the sickle cells. The knowledge of genotype is important when choosing life partners. Intending couples should know both their own genotype as well as their partner's genotype at the early stage of their relationship before they are well rooted in love and emotions.

It is important to know that for as many people that know there genotype, there are even yet many more that do not know theirs.

Possible Outcomes of Different Genetic Combination

AA + AA = AA, AA, AA, AA

AA + AS = AA, AS, AA, AS

AA + SS = AS, AS, AS, AS

AA + AC = AA, AA, AA, AC

AS + AS = AA, AS, AS, SS

AS + SS = AS, SS, SS, SS

AS + AC = AA, AC, AS, SS

SS + SS = SS, SS, SS, SS

AC + SS = AS, AS, SS, SS

AC + AC = AA, AC, AC, SS

Perfect Matches:

AA+AA= Excellent

AA+AS= Good

AA+SS= Fair

AS+AS= Bad

AS+SS= Very Bad

SS+SS= Extremely Bad

Above are the reasons for knowing your genotype before marriage. It is still important to lay emphasis so as to make the right choice for your unborn children.

People with the genotype AA are prone to malaria sickness at their early ages. Sickle cell arises when there is any blockage in the blood vessels which inhibits the flow of oxygen. When the red blood cell does not have the required oxygen, there will be changes in its original shape (disc shape) to a "Sickle-like" or "crescent-like shape", thus, the name "sickle cell". Sickle cell patients experience severe pains in body parts that lack oxygen flow. Their bone marrows will fail to produce red blood cells and this result to anemia. To save this crisis, blood is usually transfused to them.

Blood group/ Blood Types:

It is advisable that intending couples should know their blood groups before marriage.

The red blood cells that transport oxygen in the body carry two antigens, which are the A and B antigens. These antigens determine the blood group. The blood groups are designated by the letters O, A, B, AB. When the red blood cell carries only the A antigen, the blood group is ‘A’, it is ‘B’ when the blood cell has only the B antigen. When both A and B antigens are present, the blood group is ‘AB’. Finally, when there is neither A nor B antigen, the blood group is referred to as ’O’.

Here is the table that shows a cross breed of different blood groups and their products:

A + A = A or O

B + B = B or O

A + B = A, B, AB or O

A + O = A or O

B + O = B or O

A + AB = A, B or AB

O + O = O only

Blood groups have a hereditary basis and depend upon a series of alternative genes, a fact sometimes utilized in solving the problems of disputed parentage.

Note:

*O are universal donors (donate blood to all blood types). 

*AB+ are universal recipients (receive from all blood types).

*A+ can receive blood from A+, A-, O+ & O-

* A- from A- & O-

*B+ from B+, B-, O+ & O-

*B- from B- & O-

*AB- from A-, B-, AB- & O-

* O+ from O+ & O-

*O- from O-

Conclusion:

Knowing one's blood group helps a lot. It determines the donor and recipient of blood transfusion, and also helps in determining paternity. A person with one blood type or group can produce antibodies against the other. For instance, a person with blood type A makes antibodies against blood type B. If this person is given blood of type B, his or her type antibodies will bind to the antigens on the type B blood cells cause the blood to clump together. Compatibility of blood type is necessary before transfusing blood in times of accidents and emergencies.
