This article covers extensively the Basic Laws of population genetics and factors affecting the spread of hereditary diseases in society. How genetic drift, natural selection, inbriding, and migration processes affect the population gene pool has been analyzed from a scientific point of view. The epidemiology of hereditary diseases and the importance of modern genetic diagnostic and screening methods in their prevention were also revealed.

Population genetics, hereditary diseases, genetic drift, epigenetics, gene pool, mutation, screening, genome, inbriding, natural selection.
