This concept refers to stabilizing selection, a type of natural selection where individuals with traits near the average have higher fitness compared to those with extreme traits. In this scenario, individuals at the center of the curve—representing the average phenotype—are more likely to survive and reproduce, as they are better adapted to the environment. This leads to reduced variability in the population, as extreme traits are selected against. Overall, stabilizing selection promotes the maintenance of common traits while filtering out less advantageous extremes.
Stabilizing Selection
It's usually called stabilizing selection.
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
Disruptive selection.

Directional selection occurs when individuals at one extreme of a trait have a higher fitness, leading to a shift in the population towards that extreme. Disruptive selection occurs when individuals at both extremes of a trait have higher fitness, leading to the population splitting into two distinct groups.
Relative fitness plays a crucial role in determining the success of individuals within a population by measuring how well an individual's traits help them survive and reproduce compared to others in the same population. Individuals with higher relative fitness are more likely to pass on their genes to the next generation, leading to evolutionary changes within the population over time.
Directional selection, where individuals with phenotypes at one extreme of the bell curve have a higher fitness compared to others. This can result in a shift in the population towards that extreme phenotype over generations.
Directional selection. In this type of selection, the advantageous trait in a population shifts towards one extreme as individuals with that trait have higher fitness and are more likely to survive and reproduce.
Relative fitness in biology refers to the ability of an individual to survive and reproduce compared to others in the same population. It is a measure of how successful an organism is in passing on its genes to the next generation. Individuals with higher relative fitness are more likely to survive and produce offspring, leading to their genes being passed on more frequently in the population. This can result in changes in the genetic makeup of the population over time, as those with higher relative fitness traits become more common.
The ability of an individual to survive and reproduce in its specific environment is known as fitness. Fitness is a measure of how well an organism is adapted to its environment, allowing it to successfully pass on its genes to the next generation. Individuals with higher fitness are more likely to thrive and contribute their genes to future generations.
