The Human Genome Project has allowed scientists to directly genotype the sequence of human DNA nucleotides. [32] Once genotyped, genetic variants can be tested for association with a behavioural phenotype, such as mental disorder, cognitive ability, personality, and so on. [33] Candidate Genes.
It has evolved to address more complex questions such as: how important are genetic and/or environmental influences on various human behavioural traits; to what extent do the same genetic and/or environmental influences impact the overlap between human behavioural traits; how do genetic and/or environmental influences on behaviour change across ...

Outside of formal scientific inquiry, human behavior and the human condition is also a major focus of philosophy and literature. [5] Philosophy of mind considers aspects such as free will, the mind–body problem, and malleability of human behavior. [7] Human behavior may be evaluated through questionnaires, interviews, and experimental methods.
Dual inheritance theory (DIT), also known as gene–culture coevolution or biocultural evolution, [1] was developed in the 1960s through early 1980s to explain how human behavior is a product of two different and interacting evolutionary processes: genetic evolution and cultural evolution.
Behavioral epigenetics is the field of study examining the role of epigenetics in shaping animal and human behavior. [1] It seeks to explain how nurture shapes nature, [2] where nature refers to biological heredity [3] and nurture refers to virtually everything that occurs during the life-span (e.g., social-experience, diet and nutrition, and exposure to toxins). [4]
Inherited traits are controlled by genes and the complete set of genes within an organism's genome is called its genotype. [2] The complete set of observable traits of the structure and behavior of an organism is called its phenotype. These traits arise from the interaction of the organism's genotype with the environment. [3]
The following outline is provided as an overview of and topical guide to genetics: . Genetics – science of genes, heredity, and variation in living organisms. [1] [2] Genetics deals with the molecular structure and function of genes, and gene behavior in context of a cell or organism (e.g. dominance and epigenetics), patterns of inheritance from parent to offspring, and gene distribution ...
