Study Notes

Heredity

  • Heredity is the transmission of traits from parents to offspring through genes.
  • Each person inherits a unique combination of genes, influencing various characteristics.
  • These characteristics include physical traits (e.g., eye color, height), disease susceptibility, and aspects of personality and intelligence.
  • Research suggests intelligence is heritable, with genes explaining 40-80% of the variation in IQ among individuals.

Environment

  • Environment encompasses all external factors impacting development, including family, culture, education, and socioeconomic background.
  • Environmental influences can significantly modify genetic predispositions.
  • For example, a child genetically predisposed to high intelligence may not reach their full intellectual potential if raised in an environment with limited educational opportunities.
  • Conversely, supportive and enriching environments can enhance genetic potential.
