BLOOD GENETIC COMPATIBILITY AND MARRIAGE

     This is another concept that should be well noted by intending couples  regarding the nature and characteristics of blood pertaining to RBC(red blood cell). In a physical nature, blood appears to be the same but microscopic analysis shows that blood are different genetically.
     However, there are many systems that could be used to determine blood group such as ABO system, Lewis system, Duffy system, Rhesus factor system e.t.c but the most significant ones are ABO system and Rhesus factor system.
In ABO system, an individual with type A blood will react against type
B or type AB blood.
An individual with type B blood will react against type
A or type AB blood.
An individual with type O blood will react against type
A, type B, or type AB blood.
An individual with type AB blood will not react
against type A, type B, type AB, or type O blood.

Rhesus factor system
     Getting married to a partner with an incompatible blood group can result in still birth. A rhesus negative (-ve) woman shouldn't marry a rhesus positive (+ve) man while a rhesus positive woman should marry a rhesus negative man. However, if both couples have the same rhesus status, they are free from any complication (e.g rhesus isoimmunization) that could result from that.

Genetic compatibility
     Genetic compatibility is just an aspect of marriage compatibility. Will you ever forgive yourself if your children die every year?  Secondly, will you be happy spending overboard on kids that are likely not to survive in the end? If no, then, why risk it?  It is often said and it's an amazing truth that "A broken engagement/relationship is a million times better than a broken marriage". Hearken to this, if you know you're not genetically compatible with your significant other then save yourself risk of lives. Intending couples should know if they are genetically compatible with each other before agreeing to marry each other.  Types of genotype include AA AC AS SC and SS. It should be noted that AC and AS are abnormal genotypes and it is only when individuals with abnormal genotypes marry that there's a great problem. Someone with the genotype AA can marry across. That is there's no risk of having a sickler for a
child even when he or she marries an SS. But AA marrying an SS can only result in AS children and there's no hope of having a child with the genotype AA but there's no danger either. Someone with the genotype AS should only marry
someone with the genotype AA because if AS marries AS they might have a child with the sickle cell disease(a recessive disorder). Same applies when AC marries AC or AS. AC and AS combine can produce AA, AS, AC, SC, the sickle cell disease will be SC.
✳Determine the rhesus status of every new child today.
✳Get to know your genotype and spouse' genotype.
✳Prevent genetic diseases by marrying a partner with a compatible genotype.
✳Get immunized after having your first child to prevent stillbirth in the 2nd or 3rd child because 1st child is always free from Rhesus complications.
