“Love the podcast. It’s great. Truly is! But I recently just finished their last episode “till murder do us part” and Lauren Ash made a theory at the end that the mother with AB blood and the father with A blood could not have a child with B blood. But that isn’t true!!! I know it’s unrealistic for me to expect her to know about blood types since it’s been years since she had to learn it, but as someone who’s taken a class that has talked about genetics for 4 years in a row, let me give a science lesson. Blood types are slightly more complicated than normal Mendelian genetics. There are 3 alleles in blood type genetics. A, B, and i. AB blood has the A and B allele. Type O blood has 2 i alleles. But type A blood could have AA or Ai alleles. Type B blood could have BB or Bi alleles. Lauren assumed that the father had AA blood, in which case he would not be able to have a child with type B blood. But if he had Ai alleles then the mother could give a B allele and the father could give an i allele, leading to a child with Bi alleles aka type B blood. I know I shouldn’t be this bothered by it but I am. Still 5 stars though!!!”
