What form of natural selection is shown on a graph as selection against an extreme?
Directional selection is shown on a graph as selection against an extreme. This occurs when individuals at one extreme of a trait distribution have lower fitness than individuals with intermediate phenotypes or those at the opposite extreme. Over time, this can lead to a shift in the average phenotype of a population.
Which form of natural selection is shown on the chart stabilizing disruptive or directional?
To determine which form of natural selection is represented on the chart, it would be essential to examine the characteristics of the population depicted. Stabilizing selection favors average traits, disruptive selection favors extreme traits, and directional selection favors one extreme over the other. Without seeing the chart, it’s impossible to specify which type is shown, but you can identify the type by looking for these patterns in trait distribution.
Does asexual reproduction increase the chances of natural selection?
No, asexual reproduction does not necessarily increase the chances of natural selection. Sexual reproduction introduces genetic variation through meiosis and recombination, which can provide a wider range of traits for natural selection to act upon.
How was the domestication of animals and plants was appiled to the theory of natural selstion?
These plants and animals were subjected to artificial selection so that the traits humans wanted in the organisms were selected for and the organisms not having these traits were culled. This, with some modification, is a good analogue for natural selection and artificial selection shows how organisms can be shaped over time with the proper selective pressures. The selective pressure of humans in artificial selection and the selective pressure of the environment in natural selection.
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.
What form of natural selection is shown on a graph as selection against an extreme?
Directional selection is shown on a graph as selection against an extreme. This occurs when individuals at one extreme of a trait distribution have lower fitness than individuals with intermediate phenotypes or those at the opposite extreme. Over time, this can lead to a shift in the average phenotype of a population.
Is natural selection a form of adaptation?
Natural selection is what causes adaptation.
Which form of natural selection is shown on the chart stabilizing disruptive or directional?
To determine which form of natural selection is represented on the chart, it would be essential to examine the characteristics of the population depicted. Stabilizing selection favors average traits, disruptive selection favors extreme traits, and directional selection favors one extreme over the other.

What kind of selections occurs in many birds when males that build strong nests help care for young are chosen by females as mates?
This is called, sexual selection.
Which form of natural selection is most likely to play a role in speciation?
Reproductive isolation through sexual selection is often an important factor in speciation. This type of natural selection can lead to the evolution of reproductive barriers that prevent individuals from different populations from successfully interbreeding, ultimately resulting in the formation of distinct species.
Does asexual reproduction increase the chances of natural selection?
No, asexual reproduction does not necessarily increase the chances of natural selection. Sexual reproduction introduces genetic variation through meiosis and recombination, which can provide a wider range of traits for natural selection to act upon.

What are ways in which natural selection operates on ploygenic traits?
Polygenic? Natural selection usually acts on the phenotype of polygenic traits as they are suites of genes acting in concert to form a trait. If you had a trait, such as height, in two variant brothers then the aggregate would need to be selected for as the genes working in concert, but not equally well, would render different heights in the brothers which would be then visible to natural selection.
How was darwins theory translated into a theory about economic success?
Badly. The theory of evolution by natural selection has to do with the natural world and the selection of individual organisms. Social Darwinism and like ideologies are biologically mistaken as the posit a form of group selection which has nothing to do with evolutionary theory but everything to do with social ideology trying to find scientific respectability.
How does the cold spring graph differ form the normal weather graph?
how does the cold spring graph differ from the normal weather graph.
Is being the largest heron in North America important for a heron's survival?
if natural selection happens it may form a bigger breed of herrings
Who explained that evolution might have occurred in nature from simple to complex form and origin of species by natural selection?
Charles Robert Darwin, of course!
