Trait
In biology, a trait or character is a genetically inherited feature of an organism. A synonym for trait is phenotype.

Trait is a specific characteristic of an individual. For example, their hair color or their blood type. Traits are determined by genes, and also they are determined by the interaction with the environment with genes.
a trait that shows discontinuous variation, but whose inheritance is polygenic

TRAITS OF REPTILES
Alligators, dinosaurs, lizards, turtles, and snakes. All of them are one type of reptile or another. Dinosaurs, as you know, are extinct.
Traits Are Heritable
Those individuals that survive better or reproduce more will pass their superior genes to the next generation.
traits: Ways of looking, thinking, or being. Traits that are genetic are passed down through the genes from parents to offspring.
transgenic: Containing genes from another species.
Trait correlates with preference
In the paper I discuss here, the authors (Houde and Endler,1990) conduct experiments on the guppy Poecilia reticulata. They collected these fish from 7 different streams that harbor these species.
Trait. See Phenotype.
Transcapsidation. The partial of full coating of the nucleic acid of one virus with a coat protein of a differing virus. See Coat protein.
Transcription. The process of creating a complementary RNA copy of DNA.

Dicot traits:
two cotyledons in their seeds
netted venation in their leaves
petals and sepals in 4s, 5s, or some multiple thereof
vascular bundles in the stem arranged in a radial pattern like spokes of a wheel.
Complex Traits: Multifactorial
The type of inheritance we have been discussing is called simple Mendelian inheritance and the traits we have discussed are controlled by genes at a single locus. Many traits are multifactorial.
Trait
An attribute or character of an individual within a species for which heritable differences can be defined.
Family
A category in the biological classification of plants and animals coming below an order and above a genus.
Traits are usually quantified by measurement rather than counting.
Two or more gene pairs contribute to the phenotype.
Phenotypic expression of polygenic traits varies over a wide range.
Human polygenic traits include ...
Trait that has a genetic component that does not follow strict Mendelian inheritance. May involve the interaction of two or more genes or gene-environment interactions.

Traits like intelligence, or physical attractiveness, or physical ability are questions society is going to have to face.
The traits that Gregor Mendel focused his study on were the height of a pea plant, the color of pea seeds, and the shape of pea seeds.
dominant trait A trait whose phenotype is determined by a single allele at a particular locus.
dormant Having reduced metabolic and respiratory activity.
Quantitive Trait Locus
- Quantative trait locus (QTL) is a region of DNA that is associated with a particular measurable trait (e.g., plant height).
C. all traits in peas assort independently of each other.
D. the spherical seed and tall traits are linked.
E. all traits in peas are linked.
A group of traits, such as size and number of offspring, length of maturation, age at first reproduction, and the number of times reproduction occurs, that affect reproduction, survival, and the rate of population growth.

Familial trait A trait which is more common in the relatives of an affected person.

Quantitative trait
Trait that is measured on a quantitative (linear) scale. These traits are typically affected by more than one gene, and also by the environment.
quantitative trait locus A genetic locus identified through the statistical analysis of complex traits. These traits are typically affected by more than one gene, and also by the environment.
Crosses With Two Traits
Smooth seeds (S) are dominant over wrinkled (s) seeds.
Yellow seed color (Y) is dominant over green (g).
The structure of DNA that determines the expression of a trait. See Phenotype. Genus. A category including closely related species. Interbreeding between organisms within the same category can occur. GEO. Genetically engineered organism. Germ cell.
Duchenne/Becker muscular dystrophy -- the most common and severe form of muscular dystrophy; transmitted as an X-linked trait. X-linked recessive.
Offer variation in a given trait. Cline: a series of contiguous populations that exhibit gradual and continuous change of character in response to some environmental gradient.
As with much other research in genetics, studies of genes and behavior require analysis of families and populations for comparison of those who have the trait in question with those who do not.
The number of chromosomes within the nuclei of an organism's cells is a species-specific trait.
The inheritance of a particular trait that is not encoded in the nucleotide sequence.
Association (genetic): Association refers to a concurrence greater than predicted by chance between a specific allele and another trait (for example, a disease) that may or may not have a genetic basis.
character -- Heritable trait possessed by an organism; characters are usually described in terms of their states, for example: "hair present" vs. "hair absent," where "hair" is the character, and "present" and "absent" are its states.
broad classification of organisms that tend to share certain embryological traits; among these the formation of the "mouth first" (hence the name) during gastrulation, before the future anus.
New species and inherited traits are the product of evolution
Genes are the basic unit of heredity
An organism will regulate its internal environment to maintain a stable and constant condition
Living organisms consume and transform energy.
Gene flow: The exchange of genetic traits between populations by movement of individuals, gametes, or spores. It involves the spread of new variants among different populations through dispersal.
Genetics helps to explain how traits are passed from parents to their young. Understanding certain genetic concepts can be difficult for beginners. Here are some good resources for understanding basic genetics principles.
flower constancy/fidelity - a behavioral trait in pollinators that results in their visitation of flowers of the same species for some time before switching to alternative flowers; facilitates pollination ...
In a given population of organisms, there are heritable traits that enable some members to contribute a larger number of offspring than others.
Quantitative genetics. The study of the genetic basis of traits, usually explained in terms of the interaction of a group of genes with the environment ...
Phenotype the organism's expressed traits‚ what it looks like‚ how the genes are expressed
(pheno = show‚ seem‚ appear)
Phenylketonuria a genetic disorder causing inability to digest phenylalanine
(uria = urine) ...
chromosome pairs of the same length centromere position, and staining pattern that possess genes for the same traits at corresponding loci. One homologous chromosome is inherited from the organism's father, the other from the mother.
