Several studies have shown that intelligence is only passed down from one parent, and all indicate that it is the mother who contributes this mental ability.
Several studies have demonstrated that intelligence is transmitted from only one of the parents. The reason for this asymmetric inheritance lies in the chromosomes. Thus, intelligence has its roots in the genetic inheritance of the parents, but only from one of them.
In recent decades, various studies have identified a significant relationship between maternal genes and the development of higher brain function. A study conducted by the University of Cambridge in 1984 demonstrated that genes related to intelligence are passed down through the maternal line.
Women have two X chromosomes, while men only have one, which increases the likelihood of children inheriting intelligence-related genes from the mother. This study was one of the first to highlight this trend, and since then, other studies have supported the hypothesis. The scientific basis lies in the existence of “imprinted genes.” These genetic components, as described by biologists, behave differently depending on whether they originate from a male or female body.
The research team analyzed certain components, such as biochemical and genetic factors in the brain, and concluded that the mother’s genes provide much more information for the development of brain structures associated with thinking and mental operations in babies. In addition to genetics, the mother-child relationship also contributes to the development of intelligence: a child who receives affection and maternal support will have greater curiosity and problem-solving abilities.
Other factors to consider
It is important to note that intelligence is also influenced by environmental factors, such as education and early stimulation, but there are other factors as well:
- Education: The quality and quantity of education a person receives can significantly influence their intellectual development. Cognitive stimulation through teaching and learning is crucial.
- Nutrition: A balanced and nutritious diet during childhood and adolescence is essential for brain development. Nutritional deficiencies can negatively affect cognitive abilities.
- Early stimulation: Exposure to a variety of stimuli from an early age, such as educational games, reading, and creative activities, can foster intellectual development.
- Family environment: A stable and enriching family environment, where learning is encouraged and opportunities to explore and discover are provided, can enhance intelligence.
- Social interactions: Relationships with friends, family, and classmates can influence the development of social and emotional skills, which are important components of intelligence.
- Access to resources: Having access to books, technology, and other educational tools can facilitate learning and intellectual development, which is a key measure of intellectual growth.
- Mental health: An environment that promotes emotional and mental well-being is crucial, as stress and anxiety can negatively affect the ability to learn and process information.
