Practice question

In genetics, a character is defined as any observable attribute or feature possessed by an organism, such as plant height, seed colour, blood group or wing shape. Traits denote specific variants of a character, for example tall versus dwarf or yellow versus green seeds. Characters result from genotype interacting with environment, not genetic makeup itself. Mendel followed seven contrasting characters in pea, each showing discrete inheritance, enabling quantitative analysis of segregation, dominance and independent assortment that underpin qualitative and quantitative variation. Mastery ensures accurate interpretation of monohybrid and dihybrid progeny arrays, distinguishing dominance interactions from epistasis or linkage effects.
