* Multiple Allele Heredity means that a single trait is controlled by more than two alleles (alternative forms of a gene).
Let's analyze the options:
* A) Seed Texture: Seed texture (smooth or wrinkled) is typically determined by a single gene with two alleles.
* B) Skin Color in Frogs: While frogs can have various skin colors, the underlying genetics often involve a few genes with a limited number of alleles.
* C) Patterns in Andalusian Fowl: Andalusian fowl show a classic example of incomplete dominance, where two alleles interact to produce a blended phenotype. This is not the same as multiple alleles.
* D) Human Blood Types: Human blood types (A, B, AB, and O) are determined by the ABO blood group system. This system involves three alleles: IA, IB, and i. The combinations of these three alleles create the different blood types.
Therefore, human blood types are the only example listed that demonstrates multiple allele heredity.
