Directed by Ari Aster, Hereditary is a supernatural psychological horror film that follows the Graham family as they unravel terrifying secrets about their ancestry following the death of their secretive matriarch [22, 26].
At its core, heredity explains why children look like their parents, why certain diseases run in families, and why a puppy grows into a dog rather than a cat. It is the passage of genetic information—the instruction manual for building and operating an organism.
Two copies of the mutated gene (one from each parent) are required. Parents are typically "carriers"—they carry the gene but do not show symptoms. Cystic fibrosis and sickle cell anemia fall into this category. Hereditary
In the insurance sector, the Genetic Information Nondiscrimination Act (GINA) in the US protects Americans from health insurance discrimination based on data, but it does not cover life or disability insurance.
Sociologists often debate the impact of this "social heredity." While genetic heredity determines innate potential, Directed by Ari Aster, Hereditary is a supernatural
Shockingly, these epigenetic changes can be . Research on the Dutch Hunger Winter (1944-1945) showed that children of women who were pregnant during the famine were more prone to obesity and cardiovascular disease—not because their DNA changed, but because their genes were "tagged" by the environment to behave differently. These hereditary epigenetic marks can last for several generations.
At its surface, Hereditary is a domestic drama. After the death of the Graham family's secretive matriarch, Ellen, her daughter Annie (played in a career-defining performance by Toni Collette) struggles to navigate her complicated grief. Annie is an artist who creates miniature dioramas of her own life—a literal representation of the film’s central theme: a lack of agency. Two copies of the mutated gene (one from
: Certain medical conditions are inherited , such as cystic fibrosis, sickle cell anemia, or predispositions to certain cancers [15, 33]. These occur when specific genetic mutations are passed from parents to offspring [14].
(from the Latin hereditarius , meaning "to inherit") is the biological process by which a parent transmits specific physical, physiological, or even behavioral traits to their offspring. It is the fundamental mechanism that ensures the continuity of species while simultaneously allowing for the diversity that makes evolution possible.
The concept of the is humbling. It reminds us that we are biological archives of our ancestors—carrying their victories, their traumas, their resilience, and their vulnerabilities. But while the hereditary provides the script, it does not dictate the performance.
If you have a family history of a specific condition, you are not powerless. Here is a roadmap for navigating hereditary risk:
