What characteristic within populations causes natral selection to occur?
Variations within populations is what natural selection is " looking " for. That one variant of a population is somewhat better able to survive and reproduce than other variants against the backdrop of the immediate environment is natural selection.
How can you use natural selection in a sentence?
Natural selection may ultimately be his downfall.
Is eviromenntal changes drive reprodution a natural selection?
Environment IS natural selection, so a change in environment is a change in selection pressure.
What is one factor that affects natural selection and artificial selection?
Variation in the organisms under selection. In both artificial selection and natural selection there must be heritable variations that have the possibility of being in the case of artificial selection what the selector wants in the organism and in thje case of natural selection survivability and reproductive advantages.
What is the name for the process where the organism best adapted to their environment to survive?
Charles Darwin described this as "survival of the fittest". It is the central mechanism by which evolution takes place.
Which natural selection select against both extremes?
Stabilizing selection.
How does natural selection work for or against an organism?
Natural selection reduces the number of fertile offspring an organism may raise.
What is the order of natural selection?
Simply put. Mutation, variation and selection against the immediate environment.
What is natural selection like?
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
Which type of natural selection in which the mean characteristics of a population are preserved?
This type of natural selection is called stabilizing selection because the mean traits of the population are being selected for against the immediate environment.
Does natural selection cause changes in the environment?
No, natural selection is the environment! The variant organism is selected against the immediate environment where it survives and reproduces better than it's conspecifics.
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.
Is natural selection a source of variation within species?
No, mutation and sexual recombination are the sources of variation and natural selection selects from those variations presented to it against the immediate environment.
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.
Is this true Natural selection cannot operate efficiently against rare recessive alleles?
True
What process in which organisims with traits well suited to an environment are more likely to survive and to produce offspring is?
natural selection
Adaptation which allows for natural selection is called?
Adaptation does not allow for natural selection: natural selection causes adaptation.
