Single Nucleotide Polymorphisms (SNPs) and Insertions/Deletions (indels)

Single Nucleotide Polymorphisms (SNPs) and Insertions/Deletions (indels) are two types of genetic variations that are commonly found in the DNA of living organisms.
SNPs are variations that occur when a single nucleotide (A, T, C or G) in the DNA sequence is changed. These variations are the most common type of genetic variation found in humans and are responsible for the genetic differences between individuals. SNPs can occur in coding regions of genes, non-coding regions, or in regulatory regions that control gene expression. SNPs can also be used as markers for genetic studies, as they can be easily identified and used to track the inheritance of specific genetic traits.
