"The three of us have different blood types?" Xu Nianhua wasn't all that surprised. She wasn't their biological child anyway, so it made sense that her blood type would be different.
The nurse heard Xu Nianhua's words and smiled as she asked, "Are you real siblings?"
"Yep." Xu Nianji nodded firmly.
Xu Nian'an sat there, still thinking about the blood type inheritance chart.
"If your parents, one is Type A and the other Type B, then it's possible for all three siblings to be Type B, Type O, and Type AB." The nurse answered seriously.
Xu Nianji kind of got it, but not really.
Xu Nian'an heard this and suddenly everything clicked. He said confidently, "Right, right, that's totally possible. I almost got scared there."
Xu Nian'an let out a huge sigh of relief. When he first saw the three blood types, it really gave him a fright, but the nurse's explanation instantly put him at ease.
