An individuals environment, including factors such as early-life adversity, may result in changes in the way that parts of a persons genetic code are read. While these epigenetic changes do not override the important influence of genes in general, they do constitute additional ways in which that influence is filtered through nurture or the environment.

During the modern era, theories emphasizing the role of either learning and experience or biological nature have risen and fallen in prominencewith genetics gaining increasing acknowledgment as an important (though not exclusive) influence on individual differences in the later 20th century and beyond.

Inquiries into Human Faculty and Its Development. Nature proponents believe that homosexuality is genetic or outside of a person's control.
