WebGenetics refers to the study of genes, which make up our genetic material (DNA). Each gene is a set of instructions (code) to make a protein that performs specific functions in the body. Changes to a gene’s code are called mutations. Mutations can prevent a protein from functioning correctly, thus causing a genetic disorder or medical ...
