Stabilizing selection favors individuals with traits that are average or intermediate, reducing the frequency of extreme phenotypes. As a result, the distribution of phenotypes shifts towards the mean, leading to a narrower and taller bell-shaped curve on the graph. This change indicates a decrease in phenotypic variation, as the extremes are selected against, promoting a more uniform population. Over time, this stabilizing effect can enhance the fitness of the population in a stable environment.

Explain how stabilizing selection would affect a graph of the distribution of phenotypes for a trait?
Stabilizing selection would result in a graph showing a peak at the intermediate phenotype, with fewer individuals at the extreme phenotypes. This is because individuals with intermediate phenotypes are favored, leading to the reduction of extreme phenotypes in the population over time.
What does a Graph look like showing phenotype distributions for stabilizing selection?
A normal curve. A Bell curve.
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.
What is the difference between directional and disruptive selection?
I'm not sure what "stabilizing directional" selection is, but if you get out a bell curve graph... Stabilizing selection tends to select for individuals around the average, or mean, of a population, which technically makes the curve steeper. Directional selection shifts the average in one direction (shifts the whole curve in one direction). Disruptive selection creates two new averages, which means it splits the one curve into two, smaller, separate curves.
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 kind of graph is used todepict the phenotypes for a typical polygenic trait?
A histogram or bar graph is typically used to depict the phenotypes for a typical polygenic trait. Each bar represents a different phenotype, with the height or length of the bar corresponding to the frequency of individuals with that phenotype in the population.
Compare and contrast stabilizing directional and disruptive selection?
Stabilizing selection is where a population is favored by just the right amount of a certain trait, and if they don't have the right amount of that certain trait then they die. Example: Human babies and birth weight, if the baby is too small, i gets sick. If the baby is too big, it cannot get through the pelvis; but just the right weight and it will come out lively and well. Disruptive selection is when an animal has to fit in with its environment; I.E., camouflage.

It would be the one taller then the original graph. APEX
Does this selection of counters make for an effective graph Why or why not"?
The selection of counters may or may not make for an effective graph, depending on the data being represented. If the counters accurately reflect the data and are clearly labeled, then the graph is likely to be effective. However, if the counters are unclear or do not accurately represent the data, the graph may not be effective.
