How does genetic variation and environmental factors work together to cause natural selection?

Higher the genetic variation, better luck to deal with wider range of environmental factors hence better luck to pass the sieve of natural selection.
ALSO
Organisms (plants, animals, bacteria, etc) that have more traits that are favorable in the environment will live longer and have more opportunities to reproduce and create offspring that share their favorable traits. Organisms with traits unsuitable for the environment will die sooner, and will produce fewer or no offspring. If given enough time in a stable environment, the population will eventually reflect the genes best suited for it, assuming pure natural selection.

What causes varation in traits?
Genotypic variation is caused by mutation. Phenotypic variation can be caused by mutation, which gives rise to different alleles, or it can be caused by environmental factors.
What happens to a population without variation?
If all the members of a species were 100% identical (no variation) natural selection would have no effect. Members of such a species would die totally randomly with no influence from the selection pressure, so no natural selection could happen.
What environmental factors affect diffusion?
Diffusion is affected by various environmental factors, like temperature.
What is the difference between environmental factors and genetic factors?
because there not the same and there different factors
Is horse breeding an example of natural selection?
Yes, and no. Natural selection usually refers to a situation wherein alleles or organisms compete against eachother without external guidance, under the influence of mindless environmental factors. In horse breeding, the principle is almost exactly the same, but the factors influencing the differential reproductive success of alleles include the intelligent decisions of humans.

What factors could be important for a species to evolve by natural selection?
Environmental change and variation :)
How environmental factors contribute to evolution by natural selection.?
Environmental factors ARE evolution by natural selection. The immediate environment is the selector of the organisms that are differentially successful against the immediate environment.
Evolution by natural selection involves what three factors?
there is variation in traits , differential reproduction and last is heredity
What causes varation in traits?
Genotypic variation is caused by mutation. Phenotypic variation can be caused by mutation, which gives rise to different alleles, or it can be caused by environmental factors.
Why is crossing-over one of the factors that makes natural selection possible?
Crossing-over increases the genetic variation within a population, which is required for natural selection to act upon.

What is heritable variation?
Heritable variation is the variation in characteristics caused by genetic factors.
