The Genetic Architecture of Complex Traits

The genetic architecture of complex traits refers to how multiple genes and their interactions influence characteristics like height, intelligence, or disease risk. Unlike simple traits controlled by a single gene, complex traits involve many genes, each contributing small effects, combined with environmental factors. This intricate genetic setup means that variations in these genes can lead to differences among individuals. Understanding this architecture helps researchers unravel how various genetic and environmental influences work together to shape these traits, aiding in better prediction, prevention, and treatment of related conditions.
