BEFORE YOU SAY I DO...
The first thing to know is the genotype. Genotype can be simply defined as the genetic constitution of an individual organism.
The problem to avoid with genotype compatibility for intending couples is the sickle cell disease (a receive disorder)—a very serious medical condition with high prevalence rates in African south of the Sahara.
Types of Genotype:
The genotypes in humans are AA,AS, AC,SS. They refer to the haemoglobin gene constituents on the red blood cells. AC is rare, whereas AS and AC are abnormal.
Genotype compatibility chart
Study this table below carefully:
AA+AA= AA, AA, AA, AA (Excellent)
AA+AS = AA, AS, AA, AS, (Good)
AA+SS = AS, AS, AS, AS (Fair)
AA+AC = AA, AA, AA, AC. (Good)
AS + AS= AA, AS, AS, SS (Very bad)
AS+SS = AS, SS, SS, SS (Very bad)
AS+AC= AA, AC, AS, SS. ( Bad; advice needed)
SS+SS = SS, SS, SS, SS (Very bad)
AC+SS = AS, AS, SS, SS (Very bad)
AC+ SS = AS, AS, SS, SS (Very bad)
Compatible genotypes for marriage are:
AA marries an AA. That’s the best compatible. That way you save your future children the worry about genotype compatibility.
AA marries an AS. You will end up with kids with AA and AS which is good. But sometimes if you are not lucky all the kids will be AS which limits their choice of partner.
AS and AS should not marry, there is every chance of having a child with SS. AS and SS shouldn’t think of marrying.
And definitely, SS and SS must not marry since there’s absolutely no chance of escaping having a child with the sickle cell disease.
The only thing that can change the genotype is the bone marrow transplant (BMT). However it is very expensive and carries some risks.
Other things to check out for are HIV Status and Hepatitis.
As simple as they are, we need to take it seriously so as to prevent upcoming crisis in marriages.
Have a great day.

Never know someone's genotype could be changed.
