除髮色膚色外，耳垢(cerumen)也有種族之分的。646Please respect copyright.ＰＥＮＡＮＡuSFPjqSD2X

（圖2）有研究指出（Ref1)，80-95%的東亞地區人，30-50%的南亞、北美人，646Please respect copyright.ＰＥＮＡＮＡpIC5EtYX8F
耳垢均呈乾身狀態。646Please respect copyright.ＰＥＮＡＮＡHtt4SRCeIg
然而，只有3%左右的歐洲及非洲人擁有這個乾身耳垢特質。646Please respect copyright.ＰＥＮＡＮＡBykpfBzIGI

經一輪比對後，科學家認為共有四條基因對耳垢到底是濕是乾有著重大的影響力，分別為ABCC12, ABCC11, LONPL and SIAH1。646Please respect copyright.ＰＥＮＡＮＡLkveMiH8nB

（圖3）研究中的126名日本人，有88名乾身耳垢人士，38名濕身耳垢人士。646Please respect copyright.ＰＥＮＡＮＡEHNzvOjpRa

乾身耳垢88人之中，87人兩條ABCC11基因某個區域均為AA英文字母。646Please respect copyright.ＰＥＮＡＮＡZ2gWiI4dWc
646Please respect copyright.ＰＥＮＡＮＡykVvrcbgUS
而濕身耳垢38人之中，兩條ABCC11基因某個區域均為GG英文字母，又或者是一條基因為A，一條基因為G。646Please respect copyright.ＰＥＮＡＮＡcc0GSlrEtJ
646Please respect copyright.ＰＥＮＡＮＡE01NcpOJ4s
其後科學家亦證實，該基因區域的英文字母，將對ABCC11蛋白質的功用有著重大的影響。646Please respect copyright.ＰＥＮＡＮＡOTTTBRkZ6Z

耳垢是濕是乾，對健康有沒有影響暫時尚未清楚。現今開始亦有研究嘗試透過檢測耳垢的狀況來判斷人體的健康狀況，處於初步及有爭論性的階段之中。646Please respect copyright.ＰＥＮＡＮＡMlMedbvkMq
