This article studies the general laws of variability, the relationship between genetics and human health, and the types of hereditary diseases in humans and methods for their prevention. Detailed information is provided on genetic mechanisms, the molecular basis of hereditary diseases, their impact on the phenotype, and diagnostic technologies. The study shows the importance of genetic mutations, risk factors for hereditary diseases, and modern technologies for their prevention. The article provides an in-depth analysis of the human genome, epigenetics, and their impact on health.
