Definition: The word "Genetic Denim" refers to a concept or idea that suggests that certain genetic traits have been passed down from parents to children and are inherited in a way that is unique to each individual. In other words, this term means that while genes can be inherited in a genetic manner, the specific ways they affect an individual's physical appearance, behavior, or personality is uniquely determined by their parents' genes. This concept was first introduced by the British geneticist, James Watson, who identified 23 pairs of autosomal and sex-linked chromosomes within the human genome. This idea has been influential in psychology, neuroscience, and genetics research, particularly in understanding how inherited traits are passed down through generations and the impact of environmental factors on these traits.
