Within each population of sexually transmitted organisms, there is a constant exchange of genetic material; interbreeding of individuals from different populations occurs much less frequently; therefore, genetic exchange between different populations is limited. As a result, each population is characterized by its specific set of genes with a ratio of the frequency of occurrence of different alleles inherent only to this population. Under the influence of this, in individual populations, properties can arise that distinguish them from each other. Thus, the existence in the form of populations increases the internal diversity of the species, its resistance to local changes in living conditions, and allows it to gain a foothold in new conditions. The direction and rate of evolutionary changes occurring inside the species largely depend on the properties of populations. The processes of formation of new species originate in changes in the properties of individual populations.
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.
