The genotypes in humans are AA, AS, AC, SS.
They refer to the hemoglobin gene constituents on the red blood cells. AC is rare whereas AS and AC are abnormal.
Genotype Compatibility Chart:
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 + AC = AA, AC, AC, SS. ( Bad; Advice needed)
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’ll end up with kids with AA and AS which is good. But sometimes if you’re 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.
Also Know Financial Compatibility Chart:
Rich + Rich= RR (Excellent)
Rich + Poor = RP (Good)
Poor + Poor= PP (Very Bad; Advice needed)
Rich marries an Rich. That’s the best compatible. That way you secure and save your children’s future.
Rich marries Poor. You’ll end up helping each other to build and secure a better future which is good.
Poor and Poor should not marry, there is every chance of suffering yourselves and children and not being able to provide for them. Poor and Poor shouldn’t think of marrying.
