Is an organism's actual observed properties, such as morphology, development, or behavior.This distinction is fundamental in the study of inheritance of traits and their evolution.
A phenotype results from the expression of an organism's genes as well as the influence of environmental factors and the interactions between the two. When two or more clearly different phenotypes exist in the same population of a species, the species is called polymorph. The genotype of an organism is the inherited instructions it carries within its genome. This genotype-phenotype distinction was proposed by Wilhelm Johannsen in 1911 to make clear the difference between an organism's heredity and what that heredity produces Noun. 1. phenotype-what an organism looks like as a consequence of the interaction of its genotype and the environment. physical composition, composition, make-up, makeup, constitution-the way in which someone or something is composed. Translations.  Phenotype refers to observable, physical manifestations of an organism. The phenotype includes physical characteristics, behaviors corresponding to such species, structures, organs, behaviors, relfexes, etc. The genotype is the genetic programming that provides the phenotype. The phenotype is a physical manifestation of the genotype, which means that it's what happens on the outside because an organism has the gene. An example of a … phenotype would be if someone had blue eyes or something. It's a genotype.

An example of a … phenotype would be if someone had blue eyes or something. The genotype is the two-letter abbreviation thingy Phenotype. Definition. noun, plural: phenotypes. (1) The physical appearance or biochemical characteristic of an organism as a result of the interaction of its genotype and the environment. (2) The expression of a particular trait, for example, skin color, height, behavior, etc. , according to the individual’s genetic makeup and environment Definition of a Phenotype. An individual's phenotype consists of the traits we can observe. These can include features of appearance, behavior, metabolism, or anything else we can detect. On the other hand, an individual's genotype is what we call the genes that help to create that phenotype. There may be one gene at work, or more than one.  It is essential to distinguish the descriptors of the organism, its genotype and phenotype, from the material objects that are being described. The genotype is the descriptor of the genome which is the set of physical DNA molecules inherited from the organism's parents. The concepts of phenotype and genotype also demand the distinction between types and tokens. As the words “genotype” and “phenotype” suggest, these are types, sets of which any given organism and its genome are members, sets defined by their physical description. A phenotype (from Greek phainein, meaning to show, and typos, meaning type) is the composite of an organism 's observable characteristics or traits, such as its morphology, development, biochemical or physiological properties, phenology, behavior, and products of behavior (such as a bird's nest). When two or more clearly different phenotypes exist in the same population of a species, the species is called polymorph. The genotype of an organism is the inherited instructions it carries within its genome. The phenotype of an organism is the class to which that organism belongs as determined by the description of the physical and behavioral characteristics of the organism, for example its size and shape, its metabolic activities and its pattern of movement. The concepts of phenotype and genotype also demand the distinction between types and tokens. As the words “genotype” and “phenotype” suggest, these are types, sets of which any given organism and its genome are members, sets defined by their physical description. From Wikipedia, the free encyclopedia. The genotype–phenotype distinction is drawn in genetics.  Genotype  is an organism's full hereditary information.  Phenotype  is an organism's actual observed properties, such as morphology, development, or behavior. This distinction is fundamental in the study of inheritance of traits and their evolution.
