“My Dad is AA and my Mom is AA but I’m AS” — X user seeks explanation over genotype confusion

An X user has sparked conversation online after sharing confusion about their genotype.

In the post, the user wrote: “My Dad is AA and my Mom is also AA but I’m AS. Can someone make this make sense to me, please.”

The question quickly drew reactions from other users who tried to explain how genotype inheritance works.

Many pointed out that if both parents are truly AA, a child would typically also be AA, since both parents can only pass the “A” gene.

Some users suggested that the situation could be due to an earlier testing error or that one of the parents might not have been accurately tested.

Others advised the user to consider repeating the genotype test in a reliable laboratory to confirm the result.
