A non-random selection is one in which all of the people do not have equal chance of being included in the sample.
It is when you specifically choose the people that you "sample", in order to collect data about them. (As opposed to picking numbers representing people out of a hat, etc... ). For example, if you wanted to collect some sort of data from every male currently living within the same postcode as yourself, that would be nonrandom. "Non-random" varies a lot depending on what you're actually sampling. What would be "random" in one context can be "nonrandom" in another.

There are many selection tools in Photoshop including Color Range. For Tools take a look at Options Bar and move arround icons until you see pop-up tooltip Subtract from selection, then press that icon.
Natural Selection!
genetic drift, gene flow, mutation, natural selection and nonrandom mating ( sexual selection ).
Short and memorably answer. Natural selection is the nonrandom survival and reproductive success of randomly varying organisms. Natural selection is the main driver of adaptive change leading to evolution.
Theory of evolution by natural selection. Natural selection is the nonrandom survival and reproductive success of randomly varying organisms. That simple.
The main difference to remember is that natural selection is a nonrandom process while genetic drift is a random process.
Natural selection is the nonrandom survival and reproductive success of randomly varying organisms selected against the immediate environment. Like that. Remember this little explanation and you have natural selection down pat
That forces are natural selection, mutation, gene flow, nonrandom mating, and genetic drift.
The theory of evolution by natural selection. Evolution is a fact explained by the theory. Short explanation. Natural selection is the nonrandom survival and reproductive success of randomly varying individuals.
A simplified explanation. Natural selection is the nonrandom survival and reproductive success of randomly varying organisms who by this reproductive success change the allele frequency over time in populations of organisms, which is evolution.
natural selection nonrandom mating size of population genetic drift gene flow
Non-random mating is otherwise known as sexual selection. Some see this as distinct from natural selection, but I think that sexual selection is merely a form of, or perhaps more a complication of natural selection. Selection, natural or sexual, is the effect that "guides" evolution, that allows evolution to produce populations suited to their environment.
The book, On The Origin Of Species, " suggested " that organisms evolve through the process of natural selection. The nonrandom survival and reproductive success of randomly varying organisms
I know of 5: natural selection mutation genetic drift gene flow (migration) and im pretty sure nonrandom dating is one
