摘　　要：目的:研究人类手掌小鱼际区真实花纹的家系特点,了解人类手掌小鱼际区真实花纹的遗传方式。方法:在湘南学院护理学专业学生中随机选取5个手掌小鱼际区有真实花纹(斗形纹或箕形纹)的学生,并以其为先证者进行家系调查。结果:发现手掌小鱼际区真实花纹在五个家系中表现单基因性状的系谱特点。结论:手掌小鱼际区真实花纹可能属于常染色体显性遗传。Objective：To study the pedigree character of the true pattern in palmar hypothenar area, and study the genetics of the true pattern in human palmar hypothenar area. Methods： Five students with true pattern （whorl or loop） in palmar hypothenar area were randomly chosen from the nursing department of Xiangnan University. Their pedigrees were analyzed as they were taken as the probands. Results： The true pattern in the palmar hypothenar area showed the pedigree character of monogenic trait in 5 families. Conclusion： The genetics of the true pattern in human palmar hypothenar area may belong to autosomal dominant inheritance.
