👉 Resequencing is a process in genetics where an organism is divided into two or more genetically distinct groups, with each group having its own unique genetic information and characteristics. This allows for the study of how different populations of organisms differ from one another and can be used to understand the genetic diversity within species. In practice, resequencing involves using techniques such as PCR (Polymerase Chain Reaction) or other DNA sequencing technologies to amplify a gene or sequence of genes in the genome of an organism.
