How does genetic variation support Natural Selection?
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.
What is stabilizing evolution?
A mechanism (most common) of natural selection where overall genetic diversity decreases due to particular trait or genotype getting 'fixed' into the population. It is usually represented as a parabola on a graph.
What is the process that allows for genetic diversity in populations is?
Sex.
Is the population bottleneck an example of natural selection?
No. Population bottleneck refers to a period in which the size of a population becomes much reduced, thereby reducing the number of alleles in the gene pool - and thus genetic diversity.
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.
Stabilizing selection results in more or less genetic diversity?
Stabilizing selection results in less genetic diversity in a population.
What is Stabilizing Selection and Distruptive selection?
A type of natural selection in which genetic diversity decreases as the population stabilizes on a particular trait value.
Why do you think gene pool diversity is important?
if a gene pool is restricted hereditary faults can be emphasized
True or false natural selection does not always result in an increase in genetic diversity?
true
What is three reasons why a sexual reproduction is beneficial?
genetic diversity more efficient natural selection
Which evolutionary force decrease the genetic diversity of a population by increasing the population of similar individuals?
stabilizing selection
How might using mass selection and inbreeding hurt a species' chances for survival?
Because it will decrease the genetic diversity of the population.
How is genetic variation important to natural selection and adaptation?
identical
How is genetic diversity beneficial a species?
Crossing over causes genetic diversity. If there was no genetic diversity in a species, the species would be prone to extinction.
How is genetic diversity to beneficial to a species?
Crossing over causes genetic diversity. If there was no genetic diversity in a species, the species would be prone to extinction.
How is genetic diversity beneficial to species?
Crossing over causes genetic diversity. If there was no genetic diversity in a species, the species would be prone to extinction.
What is the cause of stabilizing selection?
The type of selection that removes the fringe from both ends of phenotype distribution and establishing a means or average. Genetic diversity decreases and there is a stabilization on a particular trait.
