genetic variations

Genetic variations are differences in the DNA sequences among individuals. These differences can affect traits like eye color, height, or how your body responds to medicines. Variations occur naturally and arise from changes in the genetic code, which can be inherited or happen spontaneously. They help explain why people are unique and contribute to diversity within populations. Most variations are harmless, but some can influence health or disease risk. Overall, genetic variations are a key part of human diversity, shaping our physical features and how our bodies function.
