Abstract

Occurrence of sticky and dry cerumen was determined in 483 Indians from various tribes of the United States. The elevated frequencies of the allele for dry cerumen, found in Indians of pure ancestry, support the theory of the mongoloid origin of the American Indian. Potential application of cerumen quality as a marker for genetic and anthropological studies is discussed.

摘要

对来自美国不同部落的483名印第安人进行了黏性和干性耵聍发生率的测定。在纯血统印第安人中发现的干性耵聍等位基因的高频率，支持了美洲印第安人源自蒙古人种的理论。文中还讨论了将耵聍质量作为遗传和人类学研究标记的潜在应用。
