1 Temperate highland tropical climate with dry winters (Cwb, Cwc) is a type of climate characteristic of the highlands inside the tropics of Mexico, Peru, Bolivia, Madagascar, Zambia, Zimbabwe and South Africa, but it is also found in central Argentina, outside the tropics.
Like the earwax glands, the mammary glands are also a form of the apocrine gland and express the ABCC11 gene. The C variant of ABCC11 associated with wet type earwax is also associated with colostrum secretion from the mammary glands (4).
Wet earwax is believed to have uses in insect trapping, self-cleaning, and prevention of dryness in the external auditory canal of the ear. It also produces an odor and causes sweating, which may play a role as a pheromone.
