What else can I help you with?
Why does the environment act on natural selection?
I know of no government that acts, in any direct or significant way, on natural selection.
Can natural selection occur without variation in a population?
no there is no genetic variation for natural selection to act upon
Does natural selection act on genotypes?
Indirectly, yes it does. But it can only act on genotypes through their phenotypes.
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.
What requires natural selection to occur in a population?
Natural selection requires variation in traits within a population, heritability of those traits, and differential reproductive success based on those traits. Without these components, natural selection cannot act on a population.
What level does natural selection occur at?
natural selection occurs when animals need it
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.
Can natural selection occur without variation in a population?
no there is no genetic variation for natural selection to act upon
What does natural selection only act on?
It acts on populations.
Does natural selection act on genotypes?
Indirectly, yes it does. But it can only act on genotypes through their phenotypes.
Why does natural selection act on the phenotype and not the genotype?
in need helpl asap
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.
Why is genetic variation important for natural selection to drive evolution?
Genetic variation is important for natural selection to drive evolution because it provides the raw material for natural selection to act upon. Without genetic variation, there would be no diversity in traits for natural selection to favor or eliminate, and evolution would not be possible.
Is it true natural selection can act upon an individuals genotype the external of genes?
False
Can natural selection act on a population with no variation traits?
The trait is the same for all organisms.
What requires natural selection to occur in a population?
Natural selection requires variation in traits within a population, heritability of those traits, and differential reproductive success based on those traits. Without these components, natural selection cannot act on a population.
