It acts on populations.
What else can I help you with?
Does natural selection act on genotypes?
Indirectly, yes it does. But it can only act on genotypes through their phenotypes.
Is inheritance a requirement for natural selection?
Yes it does. Without variance in the organisms genome, that gives variance to the phenotype, there would be nothing for natural selection to select from.
WHAT NATURAL SELECTION CAN ONLY ACT ON WHICH TRAITS?
Natural selection can only act on traits that have a genetic basis, meaning they are heritable and can be passed from one generation to the next. These traits must also affect an organism's fitness, influencing its ability to survive and reproduce in its environment. Additionally, natural selection operates on phenotypic traits, which are the observable characteristics resulting from the interaction of genetics and the environment. Traits that are not expressed or that do not impact survival and reproduction are not subject to natural selection.
Does natural selection act on the phenotype?
yes
Why does the environment act on natural selection?
I know of no government that acts, in any direct or significant way, on natural selection.
What is the only thing that natural selection can act on?
The phenotype or genome of the individual organism. Remember, individuals are selected, populations evolve.
Can natural selection occur without variation in a population?
no there is no genetic variation for natural selection to act upon
Why does natural selection act on the phenotype and not the genotype?
in need helpl asap
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.
Which does natural Which does natural selection affect?
natural selection is basiclly only the strong survive which means it effects the weak by killing them but bernifits the strong
Can natural selection act upon sperm cells?
From the papers I am reading there may be mechanisms to insure only top quality sperm make it into the ejaculate.
Is natural selection a process or a result of a process?
Natural selection is only the result of changing environments, mutation and the variation resulting therein. Natural selection is the process of adaptive change and the main mechanism of evolution that leads to speciation. Natural selection is a process as mutation and variation are grist to the mill of natural selection.
