Genetics is the branch of biology that studies how traits are passed on from one generation to the next and why there are similarities and differences between related individuals. Prior to the discovery of genes, scientists knew that parents passed something down to their offspring, but they did not know how or what. Gregor Mendel’s famous experiments with peas indicated that certain features, such as pea texture and flower color, are encoded by two sets of traits and that the parental traits can be separated. Decades later, scientists discovered that parents passed down DNA, which was present in chromosomes. Since the discovery of DNA, we have come to appreciate the importance of chromosomes. Genomics is a relatively new field with the bold aim of understanding the function of every single gene in a genome, including the human genome. This field took off with the completion of the first sequenced genome, and after the completion of the Human Genome Project, it has attracted increasing research. Mendelian…
