Directional Selection
Disruptive Selection
Stabilizing Selection
Directional Selection: A type of natural selection in which individuals at one extreme of a trait have a higher fitness and are therefore more likely to survive and reproduce, leading to a shift in the population towards that extreme.
Disruptive Selection: A type of natural selection in which individuals with extreme traits at both ends of a spectrum have higher fitness than those with intermediate traits, leading to the population becoming divided into two distinct groups.
Stabilizing Selection: A type of natural selection in which individuals with intermediate traits have higher fitness than those at the extremes, resulting in the population becoming more uniform and consistent in their traits over time.
