Genetic Variations

Genetic variations are differences in DNA sequences among individuals within a species. These variations can arise through mutations, recombination and other genetic processes and may involve single nucleotide changes, insertions, deletions or larger structural differences in chromosomes. Genetic variations contribute to diversity in traits, influence susceptibility to diseases and enable populations to adapt to changing environmental conditions.
