A big test came up, and for the first time in a long time, Sindy wasn’t afraid to take it. She felt ready. But during the test, there was one question that tripped her up. It asked to make a chart of possible blood types for children based on their parents’ blood types.
Sindy remembered her parents talking about their blood types before, so she used that information to make the chart. According to her chart, her blood type shouldn’t be possible given her parents’ types. Something was off.
