This is called Mendelian inheritance, after Gregor Mendel (18221884).Exercises 12.56 to 12.59 are based on the following information about Mendelianinheritance of blood type.Each of us has an ABO blood type, which describes whether two characteristicscalled A and B are present. Every human being has two blood type alleles (gene forms),one inherited from our mother and one from our father. Each of these alleles can be A,B, or O. Which two we inherit determines our blood type. Here is a table that showswhat our blood type is for each combination of two alleles:Alleles inherited Blood typeA and A AA and B ABA and O AB and B BB and O BO and O OWe inherit each of a parents two alleles with probability 0.5. We inherit independentlyfrom our mother and father.
