Genetic predisposition refers to the increased likelihood of developing certain traits or conditions based on an individual's genetic makeup. This means that specific genes inherited from parents can influence the risk of diseases, such as diabetes or heart disease, even if the individual does not exhibit symptoms. While genetic predisposition can play a significant role in health, it does not guarantee that a person will develop a particular condition. Environmental factors, lifestyle choices, and other influences also contribute to overall health, making it essential to consider both genetics and surroundings in understanding disease risk.
