Complex trait analysis

Complex trait analysis studies traits influenced by many factors, including multiple genes and environmental conditions. Unlike simple traits (like blood type), complex traits such as height, intelligence, or risk for certain diseases result from the combined effect of many small genetic variations and environmental influences. Researchers use statistical methods to identify these genetic contributions and understand how they interact with each other and with the environment. This helps in predicting risks and developing personalized approaches to health and other areas, recognizing that complex traits are shaped by a network of many interconnected factors.
