Some people are interested in the question of what is a phenotype. This definition can be considered from two perspectives. Speaking superficially, the phenotype is an external representation of the organism, which is determined by any combination of manifestations of the genotype. Having examined this definition in more detail, we can say that these are some of the features that certain genes regulate.
Characteristics characteristic of the phenotype are manifested in humans at different stages of development. The formation of these characteristics occurs under the influence of certain environmental factors and the human genotype.
Many of the molecules and structures of the individual’s body, which are included in the extended phenotype and are encoded using genetic material, cannot be detected in the external image of the body. For example, the blood type cannot be determined externally. Therefore, all the characteristics of the phenotype are determined using specialized equipment, as well as through medical, diagnostic and technical procedures.
Phenotype - this is the behavior and reaction of the body to environmental influences, which are acquired over time, depending on certain factors. For example, a beaver dam can be considered a phenotype. From the wide variety of phenotype characteristics, two characteristic features can be distinguished - sensitivity and multidimensionality. The first trait is responsible for the “removal” of certain genetic information in response to some environmental factors. Also, this phenotype trait is responsible for the degree of sensitivity to similar factors. A characteristic that determines the exact number of variants of the “removal” of information from genes towards 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 richer than that of any bacteria, so the first is more inherent in multidimensionality and sensitivity.
The phenotype of living things depends on factors such as genotype, environmental effects and random changes in the body due to the mutation. In the event that the influence of one factor on a particular characteristic is greater, the effect of other factors, respectively, decreases. For example, eye color depends on the genotype, and twins may have differences in characteristics such as height and weight, which are determined due to the influence of certain environmental factors. Also, under the influence of external factors, hepatitis C disease (genotype 1) can be acquired.
In our environment is a large number of diverse phenomena, such as phenotype. This diversity can serve as a prerequisite for the evolutionary development of living things and natural survival. An example is pine trees, which in different conditions look different: in the forests they are slender and tall, and in the fields and on the rocks they are more spreading.
