Genetic Variants
Genetic variants are differences in the DNA sequence among individuals. These variations can occur in a single gene or across entire chromosomes and can influence traits such as eye color, height, or the risk of certain diseases. While some variants are harmless, others can affect how our bodies function or respond to medications. Scientists study these variants to better understand genetics, evolution, and health. Essentially, they are the building blocks of diversity within a species, contributing to why each person is unique.

Genetic variants are differences in the DNA sequence among individuals. These variations can be as small as a single change in a gene or involve larger sections of DNA. Some genetic variants have no effect on health, while others can influence traits, such as eye color or susceptibility to certain diseases. They play a crucial role in evolution and the diversity of living organisms. Understanding genetic variants helps researchers investigate how genetics contribute to health conditions and guide personalized medicine approaches.
