Shopping on line can be easy, simple and save you lots of money. It can also take a lot of your time, frustrate you, and result in unwanted purchases. Now the same can be said for regular high street shopping, but with the vast opportunity presented by the Internet it will pay you to spend a few minutes reading this and understanding how to better optimize your Phenotype shopping experience:
1. Compare - without doubt the biggest advantage that the Phenotype offers shoppers today is the ability to compare thousands of Phenotype at a time. This is a great thing, but not necessarily all the time! Too much can be daunting at times so take advantage of the great comparison sites and where possible let them do the hard work for you.
2. Research - if it has been said it will be on the internet. Ignorance is no longer a justifiable reason for buying the wrong thing. Take the time to research in detail everything that you could possible want to know about
3. Testimonials - don't know anybody that has bought a Phenotype? Wrong! If the Phenotype is good the internet will let you know. Use the Internet as a friend and get testimonials before you buy.
4. Questions - Got a question about Phenotype then search the Forums, FAQ's, Blogs etc. Don't be afraid to ask .....
5. Reputation - Never heard of the company selling Phenotype? Don't worry, no reason why you should know every company in the world, but you know someone that does! Use the internet to find out what people are saying about Phenotype and build up a picture of their reputation for sales, returns, customer service, delivery etc.
6. Returns - still worried that even after all of the above your Phenotype wont be what you want? Check out the returns policy. There is so much competition now that someone, somewhere is bound to offer the terms that you are comfortable with.
7. Feedback - happy with your Phenotype then let people know, after all you are depending on others people input in your buying decision, so why not give a little back.
8. Security - check for the yellow padlock on the Phenotype site before you buy, and the s after http:/ /i.e. https:// = a secure site
9. Contact - got a question about Phenotype, or want to leave a comment then check out the sites contact page. Reputable companies have them and respond.
10. Payment - ready to pay for your Phenotype, then use your credit card or PayPal! Be aware of companies that don't accept them, there may be genuine reasons but given the huge amount of choice you have when buying online there is no reason at all not to buy via credit card or PayPal.

The
phenotype describes the total physical appearance of an
organism, as opposed to its
genotype. 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.Churchill F.B. 1974. William Johannsen and the genotype concept.
J History of Biology 7, 5-30.Johannsen W. 1911. The genotype conception of heredity.
American Naturalist 45, 129-159 The distinction is similar to that proposed by August Weismann, who distinguished between germ plasm (heredity) and
somatic cells (the body). A more modern version is
Francis Crick's Central dogma of molecular biology.
Despite its seemingly straightforward definition, the concept of the phenotype has some hidden subtleties. In the first place, most of the molecules and structures coded by the genetic material are not visible in the appearance of an organism, yet is part of the phenotype. Human blood groups are an example. Therefore, by extension, the term phenotype must include characteristics that can be made visible by some technical procedure. A further, and more radical, extension would add inherited behaviour to the phenotype.
Secondly, the phenotype is not simply a product of the genotype, but is influenced by the environment to a greater or lesser extent (see also
phenotypic plasticity). And further, if the genotype is defined narrowly then it must be remembered that not all heredity is carried by the Cell nucleus. Mitochondria, for example, divide in unison with the nucleus, but transmit their own DNA directly, not via the nucleus.
The phenotype is composed of
trait (biology) or characteristics Sydney Brenner and Jeffrey H. Miller. 2002.
Encyclopedia of Genetics San Diego: Academic Press.. Some phenotypes are controlled entirely by the individual's gene. Others are controlled by genes but are significantly affected by extragenetic or environmental factors. Almost all humans inherit the
capacity to speak and understand language, but which language they learn is entirely an environmental matter.
Phenotypic variation
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. Without phenotypic variation, there would be no evolution.
The interaction between genotype and phenotype has often been conceptualized by the following relationship:
genotype + environment → phenotype
A slightly more nuanced version of the relationships is:
genotype + environment + random-variation → phenotype
An example of random variation in
Drosophila flies is the number of
ommatidia, which may vary (randomly) between left and right eyes in a single individual as much as they do between different genotypes overall, or between
cloning raised in different environments.
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 (of this distinction).
According to the autopoiesis notion of living systems by Humberto Maturana, the phenotype is epigenetically being constructed throughout ontogeny, and we as observers make the distinctions that define any particular trait at any particular state of the organism's life cycle.
The idea of the phenotype has been generalized by Richard Dawkins in
The Extended Phenotype to mean all the effects a gene has on the outside world which may influence its chances of being replicated. These can be effects on the organism in which the gene resides, the environment or other organisms. For instance, a
Beaver#Dams might be considered a phenotype of
beaver genes, the same way beaver's powerful
incisor teeth are phenotype expressions of their genes.
The concept of phenotype can be extended to variations below the level of the gene that effect an organism's fitness. For example, silent mutations that do not change the corresponding amino acid sequence of a gene may change the frequency of
guanine-cytosine base pairs (GC content). These base pairs have a higher thermal stability ("melting point", see also DNA-DNA hybridization) than adenine-thymine, a property that might convey, among organisms living in high temperature environments, a selective advantage on variants enriched in GC content.
