How does genetic variation support Natural Selection?
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.
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.
One of the major elements of natural selection is that all?
All species have genetic variation. ;D
In order for evolution by natural selection to occur what has to happen?
There must be genetic variation, the variation must be heritable, and there must be differential reproduction (due to competition).
What are the phases of Natural Selection?
The four stages are: Overproduction, Genetic Variation, Struggle to Survive, and Successful Reproduction
Is Natural selection a source of genetic variation in a population?
No, natural selection works on that genetic variation presented to it.
What do stabilization selection and disruptive selection have in common?
They both decrease genetic variation. Stabilizing selection and disruptive selection reduce genetic variation
How does genetic variation support Natural Selection?
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.
Asexual reproduction increases genetic variation-the raw material on which natural selection operates?
Asexual reproduction decreases genetic variation which is the raw material on which natural selection operates. This is because asexual reproduction produces identical offspring to the parent.
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
Genetic variation is a necessary condition of which process?
Genetic variation is one of the conditions required for Natural Selection to occur.
What do stabilizing selection directional selection have in common?
They both decrease genetic variation .
Cows that give more milk than other cows are an example of?
Natural variation, natural selection, artificial selection, genetic engineering, etc.
Which type of selection tends to increase genetic variation?
Natural Selection.
What is the signifiance of the genetic variation and natural selection?
genetic variation (from any of several sources) provides options to try.natural selection determines which of those options help the population most.
What id genetic variation?
Genetic Variation is a measure of the genetic differences there are within populations or species. For example, a population with many different alleles at a locus may be said to have a lot of genetic variation at that locus. Genetic variation is essential for natural selection to operate since natural selection can only increase or decrease frequency of alleles already in the population
