Why Can't I Ever Get A Full Mark In A Test?

Ever notice how DNA tests are the only exams where missing 1 out of 46 chromosomes turns your life into a genetic sitcom? The meme perfectly captures that moment when you're devastated about missing one point on your test, while someone with Down syndrome (who has that extra 21st chromosome) is just living their best genetic life. Genetics doesn't care about your GPA—it's playing the long game of evolution where "perfect scores" are actually boring. Next time you're crying over that 98%, remember somewhere a geneticist is saying "thank goodness for mutations, or we'd all still be single-celled organisms comparing mitochondria sizes."
