Phenotypes are signs of the development of the body or the effect of the environment?

Some people are interested in the question of what a phenotype is. This definition can be considered from two perspectives. To put it superficially, the phenotype is an external representation of the organism, which is determined by some combination of manifestations of the genotype. Having considered this definition in more detail, we can say that these are some of the signs regulated by certain genes.

Characteristics characteristic of the phenotype, appear in humans in different stages of development. The formation of these characteristics occurs under the influence of certain factors of the environment and the human genotype.

Many molecules and structures of the organism of the individual that enter the expanded phenotype and are encoded by genetic material can not be detected in the external image of the organism. For example, the blood group can not be determined externally. Therefore, all characteristics of the phenotype are determined with the help of specialized equipment, as well as through medical, diagnostic and technical procedures.

The phenotype is the behavior and response of the body to the effects of the environment, which are acquired over time, depending on certain factors. For example, a dam of beavers can be considered a phenotype. From the great variety of characteristics of the phenotype, two characteristic features can be distinguished: sensitivity and multidimensionality. The first feature is responsible for "taking out" certain genetic information in response to certain environmental factors. Also, this feature of the phenotype is responsible for the degree of sensitivity to such factors. A characteristic that determines the exact number of variants of "removing" information from genes towards the factors and characterizes precisely those aspects to which the phenotype is particularly sensitive is multidimensionality. These characteristics are responsible for wealth. In other words, the greater the multidimensionality and sensitivity, the richer the phenotype. For example, the phenotype of a person is more rich than that of any bacterium, so the first is more inherent in its multidimensionality and sensitivity.

The phenotype of living beings depends on factors such as the genotype, the environmental impact and random changes in the organism due to mutation. In the event that the influence of one factor on a certain characteristic is greater, the impact of other factors, respectively, decreases. For example, the color of the eye depends on the genotype, and twins can have differences in characteristics such as height and weight, which are determined by the influence of certain environmental factors. Also, under the influence of external factors, one can acquire a hepatitis C disease (genotype 1).

In our environment there is a large number of diverse phenomena, such as a phenotype. This diversity can serve as a prerequisite for the evolutionary development of living beings and natural survival. As an example, you can find pines that look different in different conditions: they are slender and tall in the woods, and in the fields and on the rocks they are more sprawling.
