Genomic variation refers to the differences in the DNA sequences among individuals within a species. These variations can occur in various forms, such as single nucleotide polymorphisms (SNPs), insertions, deletions, and larger structural changes. Such differences contribute to the unique traits and characteristics of each individual, influencing everything from physical appearance to susceptibility to diseases. Understanding genomic variation is crucial for fields like genetics, medicine, and evolutionary biology. It helps researchers identify genetic factors associated with specific conditions, develop personalized treatments, and study how species adapt over time. By analyzing these variations, scientists can gain insights into human health and biodiversity.
