What is Genomics?
Methods
The single base changes are represented by the letters A, T, C and G. When a genome copies, or new cells are made, sometimes a single base pair gets changed, left out, or substituted. This creates SNPs. For example, a sequence of ATC could change to GTC, in the chromosome, in just one generation. Therefore, genotyping is vitle to finding these genetic variations between generations (Weigel 1).
