Which of these is necessary for natural selection to occur genetic engeneering genetic variation asexual reproduction or enviormental stability?
Genetic variation
Is Natural selection a source of genetic variation in a population?
No, natural selection works on that genetic variation presented to it.
What does natural selection directly work on?
Natural selection acts on the genotype, but indirectly, through the phenotype.
Can natural selection occur without variation in a population?
no there is no genetic variation for natural selection to act upon
How does natural selection enhance or reduce the variability of a species?
Natural selection doesn't reduce variation. Variation is regulated by the rate of mutation.Natural selection reduces the chance of bad variation from being passed on and increases the chances for good variation to be passed on.
What characteristic within populations cause natural selection to occur?
Genetic variation. If there were no variation in the genes/phenotype then natural selection would have nothing to select from.
Does selection operate on the genotype or the phenotype?
Natural selection operates on the phenotype.
Genetic variation is a necessary condition of which process?
Genetic variation is one of the conditions required for Natural Selection to occur.
Which of these is necessary for natural selection to occur genetic engeneering genetic variation asexual reproduction or enviormental stability?
Genetic variation
What natural selection acts on?
Phenotype
How does genetic variation support Natural Selection?
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.
Does natural selection act on the phenotype?
yes
Natural selection causes changes in populations of organisms not individual organisms because?
differential reproductive success caused by genetic variation is necessary for the process of natural selection.
Is Natural selection a source of genetic variation in a population?
No, natural selection works on that genetic variation presented to it.
What principles includes variation and competition?
Natural selection.
What does natural selection directly work on?
Natural selection acts on the genotype, but indirectly, through the phenotype.
Can natural selection occur without variation in a population?
no there is no genetic variation for natural selection to act upon
