Oligogenic designates a mode of disease transmission that is determined by a small number of genes, each with a moderate effect. The combination of mutated alleles of two or more genes is necessary to express the phenotype. The main difference between trait and character is that a trait is a state of a character, which is a distinct variation of a phenotypic characteristic of an organism whereas a character is a recognizable feature, which helps in the identification of the organism..
