There are varying views on IQ, with one suggesting that a mother’s IQ directly impacts her child’s intelligence. This notion stems from the fact that 8 IQ-related gene pairs are located on the X chromosome. Since women have two X chromosomes while men have one, maternal genetic inheritance is considered more prominent.
Children inherit one X chromosome from each parent, thus making maternal genetic factors more prominent in IQ formation. However, this view cannot be comprehensively proven. Recent studies indicate that parental genes are not the sole determinant of a child’s intelligence.
Intelligence is influenced by various factors, with genetics playing only a partial role. Experts believe that 40% to 60% of intelligence can be attributed to genetics, while factors like environment, nutrition, and education also play pivotal roles.
Specifically, the influence of genes on children’s intelligence is approximately 20% to 40%, but this percentage increases to about 60% as they reach adulthood. This proves that, in addition to parental genetic inheritance, development, diet, and educational environment significantly contribute to a child’s intelligence.

**How to Identify Children with High IQs?**
Many experts suggest that a newborn’s initial reactions can reflect brain development and provide valuable insights into their intelligence.
**Ideal Birth Weight:**
Research shows a strong correlation between birth weight and future cognitive development. Infants weighing between 2.8 and 4 kg tend to exhibit better cognitive development than their peers.
Underweight babies are at higher risk of malnutrition, while overweight babies may face birthing complications and are more likely to develop obesity and other health issues in the future.
Thus, birth weight not only indicates a child’s health but also indirectly suggests brain development. A healthy weight indicates adequate nutrition during pregnancy, which is beneficial for future brain development.
**Smiling Infants:**
An infant’s smile is more than just an emotional expression; it can also reflect cognitive development.
Studies show a strong connection between an infant’s smile and brain development. Typically, infants start responding to external stimuli within a month of birth, indicating effective sensory and brain function development.
When an infant smiles at their mother’s voice and face, it often signifies healthy brain development and stronger cognitive and emotional responses.
This is why many parents observe their children displaying signs of “intelligence” or “quick-wittedness” from an early age.

**Well-Developed Motor Skills:**
Motor skills are crucial not only for physical health but also for cognitive development, especially hand movement abilities.
For example, if a newborn can firmly grip their mother’s finger within the first month, it demonstrates significant brain development and motor control.
Basic motor skills such as head lifting, head turning, and rhythmic hand movements while lying prone indicate healthy brain development.
The development of these motor skills positively impacts long-term physical health and stimulates brain development, particularly in regions associated with cognition and coordination.
Not only genetic and innate factors but also the educational environment at home significantly influence a child’s IQ.
**Nurturing a Child’s Intelligence:**
Many parents overlook this aspect, but the impact of the family environment on a child’s intelligence is as crucial as genetics.
A rich early education, parental attention and interaction, and a conducive home learning atmosphere significantly contribute to enhancing a child’s intelligence.
**How to Promote Cognitive Development in Young Children?**
While IQ is partially influenced by genetics, nurturing and cultivating intelligence are equally vital. Here are some aspects parents can focus on to support their child’s cognitive development:
**Provide a Balanced Diet:**
Adequate nutrition is essential for a child’s healthy brain development. Key nutrients like DHA, iron, and zinc are indispensable. DHA contributes to brain and vision development, iron plays a vital role in blood oxygen transport, and zinc bolsters the immune system and cell growth.
**Enhance Parent-Child Interaction:**
Interaction between parents and children is pivotal for stimulating emotional and cognitive development. Through eye contact, newborns sense love and attention from their parents. Verbal communication helps develop language skills and fosters strong relationships.
Physical affection, such as hugging, kissing, and hand-holding, makes children feel secure and builds trust with their parents, establishing a foundation for stable emotional development.
Physical affection and interaction between parents and children foster stable emotional development and trust.
**Create an Ideal Learning Environment:**
A child’s learning environment should spark curiosity and encourage exploration. Providing a variety of books, toys, and interactive games effectively stimulates creativity and independent learning.
The goal is to motivate children to explore their surroundings in a comfortable and enjoyable space, laying a solid foundation for future learning.
**Early Education:**
Appropriate early education is crucial for a child’s holistic development. By imparting fundamental knowledge and life skills, children gain confidence and a strong knowledge base.
Early education helps children express their needs and emotions, develop social skills and problem-solving abilities, and establish a firm foundation for future learning.
Although a child’s IQ may be influenced by genetics, their nurturing environment and education also play significant roles. Children need not worry about inheriting their IQ from their parents; instead, focus on creating a healthy, loving, and supportive environment. This way, their intelligence and potential can naturally flourish.
