By perceivable phenotypic differences I mean characteristics that can be seen or heard (e.g., skin color, voice quality, etc.) and nonperceivable phenotypic differences are characteristics that cannot be directly perceived such as differing levels of proteins, enzymes, hormones, and other biological markers. It would also be helpful if the frequencies of these differences were placed in the context of "traditional racial taxonomies". TIA.
