This passage describes the scale type trait in common carp: Carp are large freshwater fish that are often raised for food. Before a carp is cooked, its scales are usually removed. Normally, carp are covered in small scales arranged in straight rows. But carp with mirror scales have large scales arranged in scattered patches. Because mirror scales do not cover the fish's entire body, carp with mirror scales are easier to prepare for cooking. In a group of common carp, some individuals have normal scales and others have mirror scales. In this group, the gene for the scale type trait has two alleles.
