除髮色膚色外，耳垢(cerumen)也有種族之分的。643Please respect copyright.ＰＥＮＡＮＡ2XISRLfU9f

（圖2）有研究指出（Ref1)，80-95%的東亞地區人，30-50%的南亞、北美人，643Please respect copyright.ＰＥＮＡＮＡ9tRs3xQhfX
耳垢均呈乾身狀態。643Please respect copyright.ＰＥＮＡＮＡtUoF8d7Mwt
然而，只有3%左右的歐洲及非洲人擁有這個乾身耳垢特質。643Please respect copyright.ＰＥＮＡＮＡcCKTgIu8Zf

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。643Please respect copyright.ＰＥＮＡＮＡ3AuZB6uX1i

（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。643Please respect copyright.ＰＥＮＡＮＡ7GYuRBLoiy

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。643Please respect copyright.ＰＥＮＡＮＡ61yQ5bLCcg
643Please respect copyright.ＰＥＮＡＮＡgkYUAuJBDY
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。643Please respect copyright.ＰＥＮＡＮＡRmRpMjoYFb
643Please respect copyright.ＰＥＮＡＮＡXM8IB9SDLz
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。643Please respect copyright.ＰＥＮＡＮＡ2CQv1vgqKM

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。643Please respect copyright.ＰＥＮＡＮＡz1QjyCKDp0
