I'm a bit confused about my baby's blood group. My husband has a B blood group and mine is A, but somehow our baby's blood group is O. Could you help me understand why this might be? Is it something I should be worried about?

The inheritance of blood type is based on mendelian genetics. For ABO blood typing, if you are A and your husband is B, there is 25%chance of your baby being O. This might be because your genotype would be AO and your husband's might be BO. So based on probability, 25%probability each of baby being A, B, AB or O. Similarly for Rh factor inheritance, assuming you both were Rr, you have 25% chance for RH negative baby. To conclude.. its possible for a A+ and B+ couple to have O- baby.

Question

I'm really worried about my 3-year-old. He's not walking or talking yet. We've already seen a neurological pediatrician who gave us Normabrain syrup, and we've done MRI, TMS, and some blood tests, but everything came back normal. We're planning to see a genetics specialist soon. Why hasn't he started walking yet? He can walk for about 5 to 6 feet before he falls down. Could there be an issue because I married my maternal uncle's daughter?
