>However there is a difference between the balance of eccrine and apocrine glands which is based on genetics. Different racial groups have different genetic dispositions in this regard which are genetically related to the A allele (eccrine type) or G allele (apocrine). African-Americans have the highest rate of G alleles at nearly 100% (surprisingly, Africans have a slightly lower rate), while Koreans have the lowest rate at about 0%. And Japanese people have a low rate of G alleles (about 20%) and Europeans have a high rate (about 80%).Another characteristic of the G allele is damp, soft earwax while A allele people have dry and flaky earwax.
Apocrine glands have also been associated with pheromones in some studies. The glands themselves become active after puberty and sweat is often linked to sex hormones.
