What else can I help you with?
Which of these is necessary for natural selection to occur genetic engeneering genetic variation asexual reproduction or enviormental stability?
Genetic variation is necessary for natural selection to occur. This variation provides the raw material for differential survival and reproduction, which drives the process of natural selection. Without genetic variation, there would be no differences for natural selection to act upon.
Is Natural selection a source of genetic variation in a population?
No, natural selection works on that genetic variation presented to it.
Can natural selection occur without variation in a population?
no there is no genetic variation for natural selection to act upon
What is natural selection that acts against one type of extreme form of a polyygenic trait to reduce genetic variation and change the average value of a trait within a population called?
Stabilizing selection is the type of natural selection that acts against extreme forms of a polygenic trait to reduce genetic variation and maintains the average value of the trait within a population. It favors the intermediate phenotype, leading to a narrowing of the range of variation for that trait over time.
Why does cloning contradict the principles of natural selection?
Cloning contradicts natural selection because it creates identical copies of organisms, rather than allowing for genetic diversity and variation necessary for species to evolve and adapt to changing environments. Natural selection relies on genetic variation for the process of evolution to occur, which is limited in cloned organisms.
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.
Which of these is necessary for natural selection to occur genetic engeneering genetic variation asexual reproduction or enviormental stability?
Genetic variation is necessary for natural selection to occur. This variation provides the raw material for differential survival and reproduction, which drives the process of natural selection. Without genetic variation, there would be no differences for natural selection to act upon.
Genetic variation is a necessary condition of which process?
Genetic variation is one of the conditions required for Natural Selection to occur.
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
Is Natural selection a source of genetic variation in a population?
No, natural selection works on that genetic variation presented to it.
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.
What principles includes variation and competition?
Natural selection.
Which of the following is necessary for evolution to occur?
Genetic variation is necessary for evolution to occur, as it provides the raw material for natural selection to act upon. This variation can arise from mutations, genetic recombination, or gene flow.
Can natural selection occur without variation in a population?
no there is no genetic variation for natural selection to act upon
What is natural selection that acts against one type of extreme form of a polyygenic trait to reduce genetic variation and change the average value of a trait within a population called?
Stabilizing selection is the type of natural selection that acts against extreme forms of a polygenic trait to reduce genetic variation and maintains the average value of the trait within a population. It favors the intermediate phenotype, leading to a narrowing of the range of variation for that trait over time.
