Genetic studies involve the examination of genes, DNA, and heredity to understand how traits and characteristics are passed from one generation to another. Researchers analyze genetic variations to identify links between specific genes and diseases, traits, or behaviors. This field helps in understanding the biological basis of health and illness. These studies can include techniques like genome sequencing, which maps an organism's complete DNA, and genome-wide association studies (GWAS), which look for genetic variations associated with particular traits. Findings from genetic studies can lead to advancements in personalized medicine and improve our understanding of evolution and biodiversity.
