Natural selection requires that individuals in a population are?
Natural selection requires that individuals in a population are
What is the third step in natural selection?
There are really no steps in natural selection - just conditions required for it to occur.
Which type of natural selection in which the mean characteristics of a population are preserved?
This type of natural selection is called stabilizing selection because the mean traits of the population are being selected for against the immediate environment.
When will natural selection occur?
when there is competition
Why would natural selection not occur in this poplutation?
What population? Perhaps you mean if there were no variation for natural selection to select from.
How do alleles influence natural selection?
It's the other way around: natural selection is the natural process that causes the frequencies of occurence of alleles in the population gene pool to shift.
What is an independent value?
sample data drawn from one population is completely unrelated to the selection of sample data from the other population.
What is independent values?
sample data drawn from one population is completely unrelated to the selection of sample data from the other population.
What type of natural selection causes no change in the population?
If a population exists in an environment that changes very little, then natural selection may not provide any pressure to change. However, even under these conditions genetic driftoccurs, introducing random change within the parameters set by natural selection.
List the three conditions that are necessary and sufficient for natural selection to act on a?
A beneficial mutation leading to variability in a population and the heritability of those beneficial traits.
In an unchanging environment selection in a well adapted population is?
in an unchanging environment, selection in a well adapted population is?
Does natural selection work on preexisting variation in a population?
Natural selection does work on preexisting variations in a population. This is how the population was shaped to be the way that they currently are or were.
The curve on the left shows the height of a population of penguins. The curve on the right shows the population five years later. What has happened to this population?
Directional Selection - APEX
What statements presents a condition of the hardy-weinberg principle?
Very large population, isolation from other population, no net mutation, random mating, no natural selection...if these conditions are met, the status would be in equilibrium or in other words there is no change.
Which type of natural selection favors average individual in a population?
It is stabilizing selection
Natural selection requires that individuals in a population are?
Natural selection requires that individuals in a population are
Do humans have alleles?
It's the other way around: natural selection is the natural process that causes the frequencies of occurence of alleles in the population gene pool to shift.
