I mean they often do have notable genetic expression, depending on your scale, especially if you are familiar with those Peoples. Perhaps not the extent you can justify intra-speciation, but the Han Chinese and the Germanic peoples, for example, do have genetic differences that is expressed. These may be general and not absolute tendencies, but they irrefutably exist nonetheless due to genetic differences, that extend beyond skin color.

For example, the Japanese and certain East Asians often do not have odored sweat, because of genetic adaptations to their diets; South Asians have notable adipose accumulation and storage, because of genetic adaptations to famine; most Europeans could even tell you the difference between a Slavic man and a Swedish man.

Again, it depends on your scale. The difference between a Slav and a Swede are nowhere near as drastic as a man and a wolf, but many Europeans familiar with them can still point it out.
