the doctor specifically asked for type O donors other than parents and direct relatives because of ABO group genetic complexities. basically the blood components of cheng ge may not be compatible with wowo, but since cheng ge doesn’t know he is direct family, xiao mao stopped him

Correct me if I'm wrong but for a child to have O type, both parents must be O. Not sure if the manga mentioned if it's rhesus negative or positive though. so I'm this case, Cheng Ge would be the perfect match for Wo Wo's blood. I've never heard of parents with the same blood type as the child not being able to donate. If what you said is true, could please provide me a link to an article that explains it? I'm genuinely curious. Did a biomed degree for 3 years and was never taught of anything like that.
