Many parents are curious: whose gaze is visible in their son's smile - the mother's or the father's? Genetics and scientific research provide a clear but interesting answer to this question.
According to research, a person's facial expressions and muscles are complexly influenced by the genes of parents. As scientists from the University of Pittsburgh in the USA have found, babies often have maternal facial features, especially a smile and mouth expression. This is due to an evolutionary defense mechanism: babies recognize their mother more quickly and benefit from her help.
At the same time, the father's behavior and qualities are reflected in the child's smile and facial expressions. Some studies have shown that the father's influence on children's sense of humor and inclination towards laughter is significant.
In conclusion, both mother and father contribute to a son's smile, but scientifically speaking, the first and main influence comes more from the mother. Through a smile, the love and qualities of the father and mother are revealed to each other.
