When individuals at only one end of the bell curve of phenotype frequencies have high fitness the result is?
directional selection
When individuals at only one end of a bell shaped curve of phenotype frequencies have high fitness the results is?
Directional 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
When individuals near the center of the curve have higher fitness than individuals at either end of the curve?
Stabilizing Selection
What type of natural selection takes place when individuals at the upper and lower ends of the curve have higher fitness than individuals near the middle?
Disruptive selection.
What is a type of selection in which individuals at both ends of the distribution curve have higher fitness than those near the middle?
disruptive selection
The type of selection in which individuals at one end of a curve have the highest fitness is called?
Disruptive selection
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 does a Graph look like showing phenotype distributions for stabilizing selection?
A normal curve. A Bell curve.
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.
Does stabilizing selection favors average individuals?
Yes, because the two extremes of the phenotype distribution are selected against. Consider human height as an example of this type of selection and think of a normally distributed 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.
