Does a daughter's intelligence come from her father or mother?

　　A daughter's intelligence is not inherited solely from either her father or mother, but rather results from the combined influence of genes from both parents. It is also affected by various postnatal factors such as environment and education. Genes and environment together shape the final level of intellectual development. If significant delays or abnormalities in intellectual development are observed in a child, timely medical evaluation is recommended.

　　Genes related to intelligence are located on autosomes; both parents pass their intelligence-related genes to their daughter, and neither parent's genes dominate this inheritance. Through complex combinations and regulatory mechanisms, these genes provide the foundational potential for a daughter’s intellectual development.

　　The postnatal environment is equally critical to intellectual development. High-quality family education, rich cognitive stimulation, adequate nutrition, regular sleep patterns, and other factors can fully activate genetic potential and promote intellectual growth—sometimes even outweighing the impact of genetic factors.

　　To support optimal intellectual development, it is important to provide children with diverse learning experiences, ensure balanced nutrition, encourage independent exploration and critical thinking, create a warm and harmonious family atmosphere, and maintain sufficient sleep.
