What role do genetics play in development?

Genetics play a significant role in development by influencing a variety of aspects, including physical traits, temperament, and the likelihood of developing certain conditions or disorders. Genetic factors can determine characteristics such as eye color, height, and even predispositions to health issues like autism or schizophrenia. Additionally, genetics can influence behavioral traits and personality aspects, such as mood and temperament.

It's important to understand that while genetics set certain potentials or risks, they interact with environmental factors throughout an individual's life, which can further shape development. This integrative perspective acknowledges that heredity and environment together contribute to a person's overall development, rather than genetics being the sole determinant or having no impact at all.
