Question

which of the following is true regarding behavioral genetics?

a.) it is considered to be an empirical science.

b.) it describes the psychological development between heredity and environment.

c.) it is the science that describes the similarities of individuals based on how biologically related they are.

d.) it is based primarily on theory.

Explanation:

Define behavioral genetics

Using the Behavioral Genetics knowledge point
Behavioral genetics is the scientific field that investigates the relative contributions of genetic (biological) and environmental factors to individual differences in behavior, traits, and psychological characteristics.

Analyze the options

• Option a: While behavioral genetics uses empirical research, describing it simply as "considered to be an empirical science" is too broad and does not capture its specific defining focus.
• Option b: This option describes the interaction between heredity and environment, but "psychological development between heredity and environment" is vague and not the standard definition of the field.
• Option c: This option accurately defines the core methodology and focus of behavioral genetics: it studies how the similarities (and differences) among individuals correlate with their degree of biological (genetic) relatedness (e.g., using twin, family, and adoption studies).
• Option d: Behavioral genetics is heavily empirical, relying on quantitative data from family, twin, and adoption studies, rather than being based primarily on theory.

Answer:

• a.) It is considered to be an empirical science.
• b.) It describes the psychological development between heredity and environment.
• c.) It is the science that describes the similarities of individuals based on how biologically related they are. (Correct answer)
• d.) It is based primarily on theory.
