How is a population different after it has experienced natural selection?

A population is different after natural selection because some of the negative genes have been weeded out. By experiencing natural selection things like obesity, weakness, and disease will be cut from the genetic pool (after many generations of coarse). Take a look at the Nam family to get a good example of this.

Is Natural selection a source of genetic variation in a population?
No, natural selection works on that genetic variation presented to it.
What makes natural selection happen?
Natural selection is driven by differences in reproductive success between variants within the same population.
Can natural selection occur without variation in a population?
no there is no genetic variation for natural selection to act upon
What requires natural selection to occur in a population?
genetic variation
How evolution occurs via natural selection?
Evolution occurs via natural selection when certain traits become more favorable in a population over time. This is typically due to the environment or natural selection pressures in the population. Natural selection works by favoring individuals with traits that are better suited to the environment while those with less favorable traits may die off or be less likely to reproduce. Over time these favored traits become more common while unfavorable traits become less common. This process eventually leads to evolution as the population changes to adapt to its environment. The three main components of natural selection are: Variation: Individuals within a population have different traits Inheritance: Traits are passed from generation to generation Differential Reproduction: Traits that are more favorable are more likely to be passed onNatural selection is an ongoing process as the environment is constantly changing and influencing the traits of the population. It is important to note that natural selection is not a directed process and does not necessarily lead to a specific outcome. The result of natural selection is determined by the environment and the traits that are favored in the population.
Natural selection requires that individuals in a population are?
Natural selection requires that individuals in a population are
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 different species of finches on the galapagos island are believed to have arisen as a result of natural selection acting on populations of finches that had experienced?
Evolution
Is it possible for a population to undergo natural selection?
No, there is no genetic variation upon which natural selection can operate.
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.
Is Natural selection a source of genetic variation in a population?
No, natural selection works on that genetic variation presented to it.
Which type of natural selection favors average individual in a population?
It is stabilizing selection
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.
How could natural selection affect the songs that birds sing?
Through ongoing natural selection a population adapts to its enviroment
Is natural selection the only force that drives biological evolution?
No. Natural selection requires reproductive variation to work on. Besides reproductive variation and natural selection, there are various forces, biochemical as well as population dynamical, that affect the allelic composition of a population.

Natural selection is driven by differences in reproductive success between variants within the same population.
Can natural selection occur without variation in a population?
no there is no genetic variation for natural selection to act upon
