The observable physical or biochemical characteristics of an organism, as determined by both genetic makeup and environmental influences. The expression of a specific trait, such as stature or blood type, based on genetic and environmental influences. An individual or group of organisms exhibiting a particular phenotype.

The physical appearance of an organism as distinguished from its genetic makeup. The phenotype of an organism depends on which genes are dominant and on the interaction between genes and environment. All rights reserved.It is true to say however, that the closer we look at the effect of an allele the more likely we are to detect a special phenotype unmasked by dominance. Can anyone with experience help me to know what the clinical phenotype of autism is?
I am new to the medical field and I have been here for 3 months. I welcome you to my favorite choice. This field is really very satisfying while we serve others for their good. Because of the similarities and differences among people with different forms of autism, health care professionals now view autism as having a broader clinical phenotype than was once thought.
The expanded phenotype goes beyond the standard definition for autism, to include, as the DSM-IV states, a range of impairments rather than the absolute presence or absence of a certain behavior or symptom DSM The observable characteristics, at the physical, morphologic, or biochemical level, of an individual, as determined by the genotype and environment.
The observable physical or biochemical characteristics of an organism, as determined by both genetic makeup and environmental influences. The expression of a specific trait, such as stature or blood type, based on genetic and environmental influences. An individual or group of organisms exhibiting a particular phenotype. Any observable or identifiable structural or functional characteristic of an organism. Cf Genotype. Manifestation of a genotype or the combined manifestation of several different genotypes.
The discriminating power of the phenotype in identifying the genotype depends on its level of subtlety; thus, special methods of detecting carriers distinguish them from normal subjects from whom they are inseparable on simple physical examination. Phenotype is the immediate cause of genetic disease and object of genetic selection. The observable appearance of an organism which is the result of the interaction of its genetic constitution and its subsequent environmental experience.

Phenotype; The set of observable characteristics of an individual resulting from the interaction of its genotype with the environment. Unless you can take a Bovine to a lab and do a total genetic makeup on it, the evidence of its genetic constitution is revealed by its pedigree and what you can see with your eye.
EPDs are data collected on the animals performance. The performance reflected in the EPD data is influenced by the animals genotype and the environment. The best bull in the world could have poor WW data, if the cows he bred did not produce adequate milk to wean healthy calves. These are fundamental concepts and I provide them because despite their simplicity, I see statements on CT that fail to acknowledge these concepts.
Examples of Genotype & Phenotype
For example, there was a thread that diminished the importance of looking at the bulls phenotype in favor of looking at the data. My question is this: where do you put the most emphasis as a breeder in your effort to evaluate the genetic quality of a Bovine? I am not a breeder but from my understanding of genetics, I would think the order of importance unless you had a complete annotated genetic map of the animals DNA to study, would be: First, the Phenotype; Second the Pedigree: and third the data on the Bovines performance as reflected in the EPDs.
Here is why I would put Phenotype first. The Phenotype is the most direct insight into the animals genotype. Everyone is knowledgeable that in looking at a Bull that you see only those characteristics that are expressed and that defects my be hidden by the recessive genes.
Conversely, there may be superior characteristics expressed if the bull was mated to a cow that would help uncover that characteristic.
But when you look at a Bull you can only judge him as he is. Obviously if you know the cows you plan to mate him too you have more information to perform you evaluation. But in the science of genetics the dice have been rolled and what you see in the Phenotype is the result of all the genetic mechanisms having been played out. Mutations, meiosis, dominance, recessiveness, fertilization, crossing over of limbs of DNA strands, etc.
Yet I talk to breeders around here who tell me they put more value on the EPDs. To the point that they exclude bulls or cows sight-unseen.2jzgte ecu pinout
I could see that if you needed a bull just for heifers and you were interested in CE only.Phenotype from Greek phaineinmeaning 'to show', and typosmeaning 'type' is the term used in genetics for the composite observable characteristics or traits of an organism. The term covers the organism's morphology or physical form and structure, its developmental processes, its biochemical and physiological properties, its behaviorand the products of behavior.
An organism's phenotype results from two basic factors: the expression of an organism's genetic code, or its genotypeand the influence of environmental factors. Both factors may interact, further affecting phenotype. When two or more clearly different phenotypes exist in the same population of a species, the species is called polymorphic. A well-documented example of polymorphism is Labrador Retriever coloring ; while the coat color depends on many genes, it is clearly seen in the environment as yellow, black, and brown.
Richard Dawkins in  and then again in his book The Extended Phenotype suggested that one can regard bird nests and other built structures such as caddis-fly larvae cases and beaver dams as "extended phenotypes". Wilhelm Johannsen proposed the genotype-phenotype distinction in to make clear the difference between an organism's heredity and what that heredity produces. The genotype-phenotype distinction should not be confused with Francis Crick 's central dogma of molecular biologya statement about the directionality of molecular sequential information flowing from DNA to protein, and not the reverse.
Despite its seemingly straightforward definition, the concept of the phenotype has hidden subtleties. It may seem that anything dependent on the genotype is a phenotype, including molecules such as RNA and proteins. Most molecules and structures coded by the genetic material are not visible in the appearance of an organism, yet they are observable for example by Western blotting and are thus part of the phenotype; human blood groups are an example.
It may seem that this goes beyond the original intentions of the concept with its focus on the living organism in itself. Either way, the term phenotype includes inherent traits or characteristics that are observable or traits that can be made visible by some technical procedure.
A notable extension to this idea is the presence of "organic molecules" or metabolites that are generated by organisms from chemical reactions of enzymes. The term "phenotype" has sometimes been incorrectly used as a shorthand for phenotypic difference from wild typeyielding the statement that a "mutation has no phenotype".
What is an Example of a Recessive Phenotype?
Another extension adds behavior to the phenotype, since behaviors are observable characteristics. Behavioral phenotypes include cognitive, personality, and behavioral patterns. Some behavioral phenotypes may characterize psychiatric disorders  or syndromes.
Phenotypic variation due to underlying heritable genetic variation is a fundamental prerequisite for evolution by natural selection. It is the living organism as a whole that contributes or not to the next generation, so natural selection affects the genetic structure of a population indirectly via the contribution of phenotypes.Phenotypeall the observable characteristics of an organism that result from the interaction of its genotype total genetic inheritance with the environment. Examples of observable characteristics include behaviour, biochemical properties, colour, shape, and size.
The phenotype may change constantly throughout the life of an individual because of environmental changes and the physiological and morphological changes associated with aging.
Different environments can influence the development of inherited traits as size, for example, is affected by available food supply and alter expression by similar genotypes for example, twins maturing in dissimilar families. In nature, the influence of the environment forms the basis of natural selectionwhich initially works on individuals, favouring the survival of those organisms with phenotypes best suited to their current environments. The survival advantage conferred to individuals exhibiting such phenotypes enables those individuals to reproduce with relatively high rates of success and thereby pass on the successful genotypes to subsequent generations.
The interplay between genotype and phenotype is remarkably complex, however. For example, all inherited possibilities in the genotype are not expressed in the phenotype, because some are the result of latent, recessive, or inhibited genes.

The germ plasm later became identified with DNAwhich carries the blueprints for the synthesis of proteins and their organization into a living body—the soma.
Modern understanding of phenotype, however, is derived largely from the work of Danish botanist and geneticist Wilhelm Ludvig Johannsenwho in the early 20th century introduced the term phenotype to describe the observable and measurable phenomena of organisms. Johannsen also introduced the term genotypein reference to the heritable units of organisms. Article Media. Info Print Cite. Submit Feedback. Thank you for your feedback.
