NGS: alignment and sequence variations

What are sequence variations?

Biological sequence variation refers to the differences in DNA sequences between individual organisms within a species. These differences can be due to mutations, which can arise spontaneously or be induced by environmental factors such as exposure to radiation or chemicals. These sequence variations can result in differences in the characteristics of an organism, such as its physical appearance, susceptibility to disease, or response to medications. The study of biological sequence variation is important for a variety of fields, including evolutionary biology, population genomics, and medical genomics.
