Influence of heredity and environment on growth and development (CTET)

Concept of Heredity

The process of genetic properties being transmitted from one generation to another is called heredity. The study of methods and causes of generation-to-generation transmission of genetic traits is called genetics. Heredity is considered a stable social structure.
A person’s inheritance includes all the bodily structures, physical characteristics, actions or abilities that he inherits from his parents, other ancestors or species. The most important result of the heredity reproduction process is the design similar to the progeny’s organisms. Heredity rules determine the degree to which different traits are inherited with complete reliability.
Most of the parental traits are common in children. Those are called hereditary traits. Such traits are transmitted from generation to generation.

Effects of Heredity

Effect on physical symptoms

● The genetic properties of a child have an important role in determining the appearance, shape, physical formation, height, etc. of a child. The fertilized zygotes in the mother’s womb combine to form various combinations of chromosomes. In this way, different genes from each child of the same parent have more similarities in the child than others with their own or blood relatives. It is only natural for a normal and healthy child to develop more than the children who are thin, weak, sick and suffering from any kind of physical obstruction since birth. Physical deficiencies have adverse effects not only on the growth and development of health as well.

Effect on intelligence

Wisdom is defined as learning ability, adjustability, decision making ability, etc. The child whose speed of learning is high, his mental development will also be fast. How the child adjusts himself in his family, society and school depends on his intelligence. Emotional ability develops in the child in accordance with mental capacity. The type of emotions that will develop in the child has the ability to fully influence his social, mental, moral, physical and language development.  Emotionally unbalanced children are unable to pay attention in studies or in any other serious work, consequently their mental development is also affected.
The superiority of intelligence is also due to the species.

Meaning of environment

• Environment includes the living and nonliving things that an organism interact with or has an effect on it. Trees, plants and animals etc. come under the environment. In this way, the atmosphere or environment means the one who surrounds it. Animals or human beings are surrounded by water, air, vegetation, mountains, plateaus, rivers, things, etc., all of them together create the environment. It is also known as Atmosphere.
Environment has a significant impact on the development of human life. As much as heredity contributes to human development, so does the environment.

Environmental factors

The atmosphere brings all the elements that have influenced a person from the time he started his life. From pregnancy to life, many types of events affect a person’s personality and his development.
After birth, a variety of environmental factors are active to influence a child’s development. In this, the environment of the child’s home, his family members and school and neighborhood relations, etc. play a major role.
•The main factors of environment are – physical factors, social factors, economic factors and cultural factors.

Physical factors

Under this comes natural and geographical conditions. Climate influences man’s development. Where there is more winter or where there is more heat, there is no development of human beings. The people of cold regions are beautiful, fair, healthy and intelligent. Patience is also high in them. While the people of the hot state are black, irritable and aggressive in nature.

Economic Factors

Money provides many types of life facilities to a person. Poor person develops inferiority complex due to lack of facilities, which hinders the path of development. The economic environment also affects the intellectual capacity of man. It also has an impact on social development.

Cultural factors

Religion and culture highly influence the development of man. The way of eating, the way of living, the mode of worship, the way of celebrating, the way of culture, etc. are our culture. Cultures that contain a scientific perspective develop properly, but the development of society is not possible where superstition and conservatism is involved.

Educational Importance

Heredity and environment have an impact on all types of development, physical, mental, emotional, social. This is why the education of the child is also affected by it. Therefore, this type of information about the child helps the teacher in solving his / her problems. Only after understanding the child can he be given directions. Not all children studying in a class have the same physical, mental health. Physical development is associated with mental development and whose mental development is good, his education is also good.
