Phenotype
The physical properties (e.g., eye color, height, blood type) of an organism. Genotype is the largest influencing factor in the development of phenotype.
Phenotype = Genotype + Environment
A phenotype is any detectable characteristic of an organism (i.e. structural, biochemical, physiological and behavioral) determined by an interaction between its genotype and environment (see genotype-phenotype ...

a type or kind that is determined on the basis of visible traits, as distinguished from genotype, which is based on gene content

Definition of phenotype :
(1) The detectable outward manifestations of a specific genotype.
(2) The observable attributes of an organism.
(3) The physical characteristics of a living object.
Phenotype
A phenotype is an individual's observable traits, such as height, eye color, and blood type. The genetic contribution to the phenotype is called the genotype.
The phenotype of a genotype containing the dominant allele; the parental phenotype that is expressed in a heterozygote.

A resulting phenotype assumed to occur in poor nutritional condition in which a pregnant female can modify the development of her unborn child so that the child may be prepared for survival in an environment where resources are short or scarce.

Phenotype
The appearance or other observable characteristics of an organism. The phenotype expressed by an organism depends upon the particular forms of its genes (e.g. its wild-type or mutant alleles) and the environmental conditions.
phenotype The observed properties or outward appearance of a trait. The physical expression of the alleles posessed by an organism.
Phenotype: The visible and/or measurable characteristics of an organism (how it appears outwardly) as opposed to its genotype, or genetic characteristics.
Phenotype An individual's outward appearance (c.f. genotype). It is also used to incluse to describe a cellular or molecular characteristic, e.g. Blood group A and RFLP ...
Phenotype. The observable characteristics of an organism, the expression of gene alleles (genotype) as an observable physical or biochemical trait. See Genotype.
Pheromone. A hormone-like substance that is secreted into the environment.
Phenotype: The physical appearance of an individual that is the result of that individual's genotype and the interaction of the genotype with the environment during development.
Phenotype the organism's expressed traits‚ what it looks like‚ how the genes are expressed

Phenotype
The observable traits or characteristics of an organism (e.g., hair colour, weight) or the presence or absence of a disease. Phenotypic traits are not necessarily genetic. [Talking Glossary]

Phenotype The physical characteristics of an organism or the presence of a disease that may or may not be genetic.

Phenotype
- The observable characteristics of an organism as opposed to the set of genes it possesses (its genotype).The phenotype that an organism manifests is a result of both genetic and environmental factors.
Phenotype
The term coined by Johannsen (1909) for the appearance (Gk. phainein, to appear) of an organism with respect to a particular character or group of characters (physical, biochemical, and physiologic), ...
phenotype ratio = 3:1 (3full: 1 constricted)
Alleles and Loci
An allele is a gene that has more than one form. Each of the forms is referred to as an allele.
Phenotypes are always affected by their environment. In buttercup (Ranunculus peltatus), leaves below water-level are finely divided and those above water-level are broad, floating, photosynthetic leaf-like leaves.
phenotype matching A mechanism by which kin may recognize one another; individuals use kin as a referent whose phenotypes are learned by association.
PHENOTYPE - The appearance of other characteristics of an organism resulting from the interaction of its genetic constitution with the environment.
A phenotype ratio of 9:3:3:1 in the offspring of a mating of two organisms heterozygous for two traits is expected when:
A. the genes reside on the same chromosome
B. each gene contains two mutations ...
Extended phenotype: All effects of a gene upon the world where the effects influence the survival chance of a gene [Richard Dawkins].
An offspring whose phenotype differs from that of the parents.
recombinant DNA
A DNA molecule made in vitro with segments from different sources.
We now use the term phenotype when we speak of the appearance of an individual and the term genotype when we refer to the genes that individual carries for the trait in question.
An allele is said to be dominant if it expresses its phenotype even in the presence of a recessive allele. See Allele, Phenotype, Recessive. Dominant gene. A gene whose phenotype is when it is present in a single copy. Dominant(-acting) oncogene.
Contiguous genes -- genes physically close on a chromosome that when acting together express a phenotype.
The mutant phenotype can therefore be easily detected.
Back translation Use of the experimentally determined amino acid sequence of part or all of a polypeptide to determine the theoretical nucleic acid base sequence(s) which could code for it.
When a single trait is being studied, a test cross is a cross between an individual with the dominant phenotype but of unknown genotype (homozygous or heterozygous) with a homozygous recessive individual.
It's really the patients that have come into the clinic with these intersex phenotypes that have yielded the most information in terms of finding the genes, the autosomal gene specifically, ...
Phenotype is the morphological, physiological, biochemical, behavioral and other properties exhibited by a living organism. An organism's phenotype is determined by its genes and its environment.
Imprinting A phenomenon in which the disease phenotype depends on which parent passed on the disease gene. For instance, both Prader-Willi and Angelman syndromes are inherited when the same part of chromosome 15 is missing.
incompletely dominant An allele combination that produces a phenotype in the heterozygous state that is distinct from the dominant homozygote and the recessive homozygote phenotypes. Also known as semi-dominant.
[36][37] Genes encode the information necessary for synthesizing proteins, which in turn play a large role in influencing (though, in many instances, not completely determining) the final phenotype of the organism.
Phenotypic plasticity. The capacity of an individual to produce different phenotypes under different conditions. Non-genetic potential variability within the range of a single individual.
Transformed cells tend to exhibit characteristics known collectively as the "transformed phenotype" (rounded cell bodies, reduced attachment dependence, increased growth rate, loss of contact inhibition, etc).
Phenotype: the totality of characteristics of an individual: the expression of the genotype.
