The diagrams above illustrate the different types of comb found in domestic fowl, showing variation in the physical characteristics of the comb. A comb is a fleshy growth on top of the head of domestic fowl, and the different types of combs have different shapes and sizes. This variation in comb types is an example of genetic inheritance, which means that offspring inherit certain traits from their parents. The inheritance of comb type in domestic fowl is controlled by multiple genes, and the different types of combs can be used in courtship behavior by males to attract females. Therefore, the diagrams above show variation in comb types that are inherited genetically and used in courtship behavior.
