(C;C) 2 Wet earwax. Normal body odour. Normal colostrum.
(C;T) 2 Wet earwax. Slightly better body odour.
(T;T) 2.5 Dry earwax. No body odour. Likely Asian ancestry. Reduced colostrum.

This is what causes most Asians to have dry flaky earwax instead of wet earwax. It is also what causes Asians to not have body odour and not need to use deodorant. It suggests Asian ancestry, although it can also occur in white people. Unfortunately it also reduces or prevents the production of colostrum when breast feeding.
