Various genetic studies are characterized by the existence of genetic influence on criminal behavior. Research on twins also plays an important role in establishing the existence of such theories. Resume. Nature versus nurture is a framework used to examine how genetics, nature, and environmental factors influence human development and personality traits. However, nature versus nurture is not a black and white issue. There are many shades of gray where the influence of nature and nurture overlap. It is impossible to untangle these. We then discuss the complex interplay of environmental and genetic effects, and present findings on gene-environment correlations and interactions. In this chapter we also present findings regarding genetic effects in relevant constructs such as the personality trait friendliness and empathy, which could point to the underlying abstraction. Decades of research show that genes play a crucial role in the etiology of ADHD and its comorbidity with other disorders. Family, twin, and adoption studies show that ADHD runs in families. The high heritability of ADHD motivated the search for ADHD susceptibility genes. Another possible direction is the integration of human genetic data with findings from animal models of addiction endophenotypes. Reynolds et al. 2020. The substance use genetics literature is rich in rodent models of addictive behavior, for example, positive reinforcement via self-administration paradigms, withdrawal and drug avoidance, Genetics Crash Course • Genetic behavior arguments are based on the principle of inheritance, heredity • Genes, the basic unit of heredity, are located on chromosomes. Humans have pairs of chromosomes passed down from each parent. • Chromosomes are made up of DNA, and,
