Term
Genetic Factors
Definition
The general guideline of traits determined by a person's DNA
Term
Environmental Factors
Definition
Those "nonbiological" factors that are involved in a person's surroundings such as the nature of the person's parents, the person's friends, and the person's behavioral choices
Term
Spiritual Factors
Definition
The factors in a person's life that are determined by the quality of his or her relationship with God
Term
Gene
Definition
