Forms of Selection

The forms of selection can be characterized as follows:

1. Условия среды изменяются (Conditions of the environment change): This form of selection occurs when the environment changes, leading to a shift in the advantageous traits for survival and reproduction.

2. Сохраняется средняя величина показателя (The average value of the indicator is preserved): This form of selection maintains the average value of a trait within a population, without favoring extreme variations.

3. Условия среды постоянны (Conditions of the environment are constant): In this form of selection, the environment remains stable, and the traits favored for survival and reproduction remain consistent over time.

4. Происходит изменение признака (A feature changes): This form of selection involves the alteration of a specific trait within a population due to environmental pressures or other factors.

5. Происходит сохранение признака (A feature is preserved): This form of selection leads to the maintenance of a particular trait within a population over time, often due to its continued advantage for survival and reproduction.

6. Приводит к образованию нового вида (Leads to the formation of a new species): This form of selection can drive the divergence of traits within a population to the extent that a new species eventually emerges.

Types of Selection

A. Стабилизирующий (Stabilizing): This type of selection favors the average individuals in a population, leading to the reduction of extreme variations and the maintenance of the status quo.

B. Движущий (Directional): Directional selection occurs when environmental changes favor individuals exhibiting one extreme of a trait, leading to a shift in the average value of the trait over time.

These forms and types of selection play a crucial role in shaping the characteristics and diversity of populations over generations.
