Answer:
intelligence
Explanation:
Both continuous and discontinuous variations are manifestations of the phenotype. They are variations that directly affect the individual's relationship with their environment.
An individual can inherit the genes to be tall, but if he suffers from malnutrition, he will not reach the height he would have reached if he had normally nourished.
A person will usually gain weight if he eats a lot and lose weight if he is on a diet, but another person can eat as much as the first and can stay thin because of his different constitution, the result of inheritance. For example, if an individual becomes ill or not, it seems that it could be attributed exclusively to his exposure to the agents of the disease, that is, to a purely environmental effect, and instead it has been shown that it is possible to inherit the predisposition or resistance For an infectious disease. If an individual has inherited the predisposition to an infectious disease, but is not exposed to infection, do not get sick. Just as the environment influences the phenotype, it has an action on individuals.
The environment has a significant influence on the development of plants. A fertilized soil and other conditions of light and temperature will accelerate the development of plants. A species of plant that grows in a valley will have, for example, wider leaves and longer stems than the same species they offer on the mountain. Similar experiments in man are possible, that is, to demonstrate whether our intelligence is mainly due to the genes we inherit or to environmental conditions.
There are cases in which for various reasons univiteline twins have been separated and raised in different environments. It has been proven that their genetic identity remains, but the development of their personality, culture and education that has been influenced by the different environment in which they have grown. But there are other characters on which the medium, whether internal or external, exerts a non-negligible influence. The pigmentation of the skin, for example, will be more or less dark in proportion to the intensity of the solar rays received. Height is another example that depends not only on hereditary factors but also on the type of food and the period of growth.
