Abstract

A systematic study of inbreeding effects on finger dermatoglyphic ridge counts among the Ansari Muslims in rural areas of Nandigram in West Bengal portrays some significant results. The distribution of total and absolute finger ridge counts (TFRC and AFRC respectively) show wide range of variation in inbred and non-inbred series of both the sexes. The rise of mean (studied both right and left sides combined as well as separately), increase of bilateral correlation and decline of bilateral asymmetry (examined both sides separately) of dermatoglyphic ridge counts in male and female samples due to inbreeding are observed. The study further records the sexual dimorphism in distribution and inbreeding effects on these traits. This investigation also attempts to throws some light on genetics of these traits. In frequency distributions, clear modes suggest that at least a few major genes (homozygous) clearly segregate on inbreeding with lowering of heterozygotes in antimodes. The results of the present study also conform to some earlier reports from different populations.

西孟加拉邦纳迪格拉姆安萨里穆斯林人群手指皮纹脊数的两性异形、近交效应和双侧变异

一项系统研究了近亲繁殖对西孟加拉邦南迪格拉姆农村地区安萨里穆斯林手指皮纹脊数的影响，得出了一些重要的结果。总指脊数和绝对指脊数的分布(分别为TFRC和AFRC)在两性自交系和非自交系中表现出较大的差异。观察到，由于近亲繁殖，男性和女性样本的皮肤纹脊计数的平均值上升(同时研究左右两侧联合和单独研究)，两侧相关性增加和两侧不对称性下降(分别研究两侧)。本研究进一步记录了这些性状在分布上的两性二态性和近交效应。这项调查也试图对这些特征的遗传学有所了解。在频率分布中，清晰模式表明至少有几个主要基因(纯合子)在近交中明显分离，而在反模式中杂合子减少。目前的研究结果也符合一些早期的不同人群的报告。
