What is nonrandom sampling?
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.

natural selection nonrandom mating size of population genetic drift gene flow
How does nonrandom mating affect evolution?
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.
