Unlike simple Mendelian traits that have two alleles (e.g., tall vs. short), blood type is determined by :

This comprehensive guide provides an in-depth look at a classic, high-school-level genetics lab: . This lab is a staple for biology students learning to combine Mendelian genetics, codominance, multiple alleles, and inheritance patterns.

Emphasize to students that while blood typing can disprove parentage (exclusionary proof), it cannot absolutely prove parentage. Charles could still be an impostor who just happens to have Type O blood. To definitively settle the estate, the lawyers would need to run a modern DNA profiling test (STR analysis).
