Single nucleotide polymorphisms, or SNPs (pronounced "snips"), are small differences in our DNA that make each person unique. They are the most common type of genetic variation we see in humans and other living things. Here’s a simple breakdown of their importance:
Molecular Markers:
SNPs act like little markers in our DNA. These markers help scientists find differences in genes among various groups. For example, in farming, specific SNPs can help farmers identify plants that might be better at resisting diseases or producing more fruit.
Genomic Mapping:
SNPs help scientists create maps of our genes. Because we know where these SNPs are located on chromosomes, they can connect certain traits—like eye color or health risks—to specific genes. In humans, researchers use SNPs in large studies (called GWAS) to figure out if some people are more likely to get certain diseases.
Population Genetics:
Studying SNPs helps us understand how different groups of people are related and how they evolved over time. By looking at patterns in SNP differences, scientists can learn about how people moved around the world and adapted to their environments.
In short, SNPs are important for understanding how our genes vary, how traits are linked to our DNA, and how species have changed over time.
