Exploring Heritability: Genetics and Environment

This chapter critically examines heritability estimation methodologies, including pedigree models and adoption studies, particularly regarding Body Mass Index (BMI) and criminal behavior. It highlights biases in existing research and the complexities involved in understanding how genetics and environment interact within social hierarchies. Through personal anecdotes and historical contexts, the discussion emphasizes the need for improved statistical analyses to better grasp the implications of genetic influences on behavior.
