Elemental distribution in the universe is also extremely bimodal .. moreso even than the exceptions to the reproductive male or reproductive female buckets.
Everything in the universe is either Hydrogen or Helium .. save for a tiny tiny cluster of exceptions known (to astronomers) as "metals" and as "every other damn element including carbon and oxygen" to the aquatic apes.
Science is quite happy to endlessly study things with a frequency of ppm (parts per million) and less.
