change in gene frequency and subsequently acts on the genotype of the population.

Why does natural selection not directly affect genes?
Natural selection acts on the way organisms interact with one another and with their environment. The genes of organisms are not usually themselves involved in this interaction: they direct it through intermediaries such as proteins. So natural selection must work through these intermediaries to affect genes.
What comes first mutation or natural selection?
Natural selection can only work on genetic variation that already exists. So mutation comes first, then natural selection.
What process in which organisims with traits well suited to an environment are more likely to survive and to produce offspring is?
natural selection
Is adaptation part of natural selection?
Adaptation is the result of natural selection.
How can a wide range of phenotypes increase the chance that some individuals will survive in a changing environment?
by natural selection.
Why is adaptation essential to understanding natural selection?
Because adaptation is the directly visible result of natural selection.

So natural selection must work through these intermediaries to affect genes.
Does natural selection work on preexisting variation in a population?
Yes, natural selection acts on preexisting genetic variation within a population. Individuals with traits that give them a survival or reproductive advantage are more likely to pass on their genes to the next generation, leading to an increase in the frequency of those advantageous genes in the population over time.
What comes first mutation or natural selection?
Natural selection can only work on genetic variation that already exists. So mutation comes first, then natural selection.
Why does natural selection work on organisms phenotypes rather than their genotypes?
This is backward, natural selection works on genotype not phenotype.
How does natural selection work for or against an organism?
Natural selection reduces the number of fertile offspring an organism may raise.
Is natural selection a fact?
Technically, one should say that natural selection is a theory that explains a set of observations. However, the theory has been substantiated to such a degree that one might as well call it fact.
Why was Charles Darwin work important?
because he created the natural selection
Does natural selection work on a variation already present in a population?
Yes.
What is the name for the process in which the organisms best adapted to their environment survive?
Its NaTuRaL sElEcTiOn if you didn't know.
Selection acts directly on?
Selection acts directly on phenotypes.
Time why does natural selection continue to work?
Natural selection creates a stronger species that is able to live longer and produce more. It continues to work because after a few generations, the traits will become common in the population.
