The role of heredity and environment in skills training and development

Heredity is a prerequisite to the emergence of skills, maturation, adaptation to natural and social environment, education and learning.
Environmental or social and cultural requirements continue heredity by construction, acquisition and modeling through learning.
Although skills depend on heredity, they are more closely influenced by environmental factors and education.
For French psychologist Zazzo, heredity comes to the ratio of 1/5 on skills training and environmental factors with a report 4/5.
Interaction between hereditary factors and environmental factors is essential. Inheritance factors serve as conditioning skills. They refer to certain predispositions as:
- morpho-functional features of sense organs,
- nervous system-type,
- plasticity cortex,
- the ability of the cortex to form RC,
- phonation device features,
- features of bone and muscular system.
Hereditary endowment can help or not skills training: in case of low endowment, learning is hindered to a greater extent; in case of high endowment, learning is more help.
Environmental role is to exercise the hereditary potential, leading to the obtaining of performance in various activities, such as personalities with skills in certain areas.
