Phenotype
Phenotype
The observable traits or characteristics of an organism, resulting from the interaction of its genotype with the environment.
Genotype
Genotype
The genetic makeup of an organism; the actual alleles (A, B, O) inherited from the parents.
Al x B Mating
Al x B Mating
A genetic cross between two different blood types, Al and B, leading to various possible offspring phenotypes.

Study Notes
Parent Genotypes Deduced from Child Phenotypes
- Child phenotypes can reveal parental genotypes.
- For instance, in matings where one parent is Al and the other is B, children with phenotypes A2 and A2B will never appear alongside children with B or O phenotypes in the same family.
- This suggests that all six possible phenotypes (A1, A2, A2B, B, AB, O) can occur from Al x B matings.
- However, the presence of an O-type child in a family where other children are A2 and A2B would indicate different parents for the children.
