Im AC heterozygous genotype and the lady I intend to marry is SC heterozygous genotype. After three years of dating, her parent got to know this and they are not in support of our marriage plan because by mistake, she told them that Im AS which we have the probality of having SS child, but later when she told them that Im AC they said we have lied and they disagreed. They later said that they dn't even want us together wether Im AC or AS that all they want is AA. Now the lady is trying to abide with her parent motion. What advice can you give?

This is a hard one. Maybe you should just take the documents to them and have a doctor describe the chances. If you don't show evidence, then it will look like you are making it up.

I know a couple with the man being AS and the woman SC. They did the tests 3 times at 3 different labs. Before they got married, the man prayed hard and God assured him that they wouldn't have SS children. They have children now with the first being AA miraculously and the second AS.
I actually know this couple and their children and I saw the tests results with my own eyes.

I don't know your relationship with God, but all I could say is for you to pray, if you are convinced and you love this lady to withstand whatever the outcome will be, which could be positive or negative and you have the blessing of both yours and her families, then go after your heart.
