Genetic studies involve the examination of genes, heredity, and genetic variation in living organisms. Researchers analyze DNA sequences to understand how traits are passed from one generation to the next. These studies can help identify genetic disorders and contribute to advancements in fields like medicine and agriculture. By using techniques such as genome sequencing and gene mapping, scientists can uncover the roles of specific genes in health and disease. Genetic studies also play a crucial role in evolutionary biology, helping to trace the lineage of species and understand how they adapt to their environments over time.
