Variability is the occurrence of individual differences. Based on the variability of organisms, a genetic diversity of forms appears, which, as a result of natural selection, is converted into new subspecies and species. Modifiable, or phenotypic, and mutational, or genotypic variability are distinguished.
||Definition of a concept
||Variability in which changes in the properties of organisms are transmitted from parents to descendants
||Inherent in all organisms. It is more often determined by the characteristics of the organism itself. Supports natural inequality, diversity of organisms. Some of them can better resist predators, others are less susceptible to diseases. the third are better protected from the cold, the fourth have a favorable combination of all the properties listed above
||Variability in response to changes in living conditions
||Abundant nutrition can lead to accelerated growth of the body, the onset of earlier maturity, their achievement of larger sizes, and vice versa. Cultivated plant varieties, in the absence of special conditions in which they were bred by humans, lose their quality. For example, white cabbage when cultivated in hot countries does not form a head. Breeds of horses brought into the mountains or other places where the food is not nutritious become stunted
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
