It is very necessary to know your spouse genotype because of the medical implications. E get people wey dey always see am say e no dey important but genotype dey very important especially when we want choose life pattern. Na mostly people wey there genotypes na As and SS so take am very important as for people wey there own na AA I don't think if e dey important since then fit marry anybody without any complications. So e dey good if your genotype fall for AS and SS for you to know your spouse genotype before marriage.
