When individuals near the center of the curve have higher fitness than individuals at either end of the curve?
Stabilizing Selection
Type of selection that cause an increase in individuals at one end of the curve?
directional
What are the three characteristics of a supply curve?
The three characteristics of a supply curve are the slope, shift, and the curve's position. Together they help determine supply and demand trends.
Is the current US economy on the production possibility curve?
An economy can be producing on the PPF curve only in theory. In reality, economies constantly struggle to reach an optimal production capacity.
Do both monetary policy and fiscal policy shift the aggregate demand curve?
Yes. An expansionary fiscal policy, or more optimistic growth expectations in the private sector will shift the aggregate demand (AD) curve upwards. The position of the AD curve is also affected by the central bank's inflation target, if the target falls, the AD curve will shift downwards. Monetary policy influences the slope of the AD curve as well as the position. If the central bank put strong emphasis on fighting inflation and little emphasis on stabilizing output, the AD curve will be flatter. The other way around will yield the opposite result.
What is Type of selection that keeps the center of the curve at its current position?
Stabilizing selection is the type of selection that keeps the center of the curve at its current position. This type of selection removes extreme phenotypes from the population, favoring the intermediate phenotype.
When individuals near the center of the curve have higher fitness than individuals at either end of the curve?
Stabilizing Selection
Three ways natural selection picks a phenotype?
stabilizing selection: when individuals near the center of the curve have a higher fitness than individuals at either end of the cure, keeping the center at its current location but narrows the overall graph directional selection: when individuals at one end of the curve have a higher fitness than individuals at the other end, or middle, causing the entire curve to move as the character trait changes disruptive selection: when individuals at the upper and lower ends of the curve have higher fitness than individuals near the middle, causing the single curve to be cut into two These three types of selection are brought about by natural selection, so whichever one is favored, then the genes evolve in that specific direction. natural selection acts on the genotype, but the results are seen in the phenotype
What is the type of selection where individuals nears the center of a distribution curve have higher fitness than those at the extremes?
It's usually called stabilizing selection.
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 does a Graph look like showing phenotype distributions for stabilizing selection?
A normal curve. A Bell curve.
What natural selection called at extreme phenotype?
This type of natural selection is called directional selection and does not display a normal curve of expressed traits, but a heavy set of data to the left of the curve that indicates the direction of selection of the extreme phenotype.Disruptive selection is where two extreme phenotypes are maintained in a population. This curve looks like a two humped camel in it's expression of these extreme traits.
What is the type of selection in which individuals at one end of the distribution curve higher fitness than individuals in the middle of at the other end?
stabilizing selection
What type of selection is shown when the bell curve narrows over time?
Stabilizing selection, which acts against both extreme phenotypes and favors intermediate variants. Hence the narrowing of the bell curve in the middle.
What do you call the center of normal curve?
The mean.
What is the measurement from the center of a circle to the curve?
radius
Type of selection that cause an increase in individuals at one end of the curve?
directional
