  1. (biology) an organism that has characteristics resulting from chromosomal alteration (synset 110361391)
    referred to in: biological science, biology - the science that studies living organisms
    is a type of: being, organism - a living thing that has (or can develop) the ability to act or function independently
    subtypes: freak, lusus naturae, monster, monstrosity - a person or animal that is markedly unusual or deformed

    referred to in: genetic science, genetics - the branch of biology that studies heredity and variation in organisms
    is a type of: alteration, change, modification - an event that occurs when something passes from one state or phase to another
    subtypes:

    • transposition - (genetics) a kind of mutation in which a chromosomal segment is transfered to a new position on the same or another chromosome
    • gene mutation, point mutation - (genetics) a mutation due to an intramolecular reorganization of a gene
    • reversion - (genetics) a return to a normal phenotype (usually resulting from a second mutation)
    • saltation - (genetics) a mutation that drastically changes the phenotype of an organism or species
