In “People with this mutation can’t smell stinky fish” by Katherine J. Wu, she talks about a new genetic trait that is appearing in Iceland citizens. Though the gene is very rare, it still has been seen throughout the country. The mutation makes it so that people with it can’t smell unfresh fish, unlike many people. Like many genes, the gene develops over time and takes a while to spread to others. The reason that the mutation had occurred was due to a change in the TARR5 strand.
I believe that genetic coding does help understand why there might be a change in a gene in a population and that we should understand what the strands could change. Each genetic code has a different job; some can change causing mutations within an area over time.
