Sex identification from fingertip features in Egyptian population

Sex differences in the thumbprint ridge density in a central Indian population

“…Thus, even when the areas analysed for thumbprint ridge density in our study differ from that of the earlier studies, [2][3][4][5][6][12][13][14][15][16][17][18][22][23][24][25][26][27][28] the basic quantitative differences remain the same, i.e., females have a higher finger (thumb) print ridge density than males which is in accordance with earlier studies on different ethnic groups. 2,[5][6][7][8][13][14][15][16][17][18][22][23][24][25][26][27][28] Ridge thickness and furrows are the two important factors which determine the density of ridges. Cummins et al, 24 Ohler et al, 25 Kralik et al 26 and Moore 28 worked on the ridge thickness in fingerprints and showed that males have coarser finger ridges than females which suggests that males will have less ridges in a given area than females and thus a lower ridge density.…”

“…Consequently, these two characteristics of the fingerprints have been widely studied by the researchers and analysts. [2][3][4][5][6][12][13][14][15][16][17][18] The ever increasing frequency of crime has made fingerprinting an indispensable tool in the hands of investigating officers. If the sex of the individual could be established with certainty, the burden of the investigating officer would be reduced by half.…”

“…Fingerprint ridge density has been shown to be sexually dimorphic in Spanish Caucasians, 2 Spanish populations 3-5 the Sardinian population, 6 Egyptian, 16 Chinese, Malaysian 15 and some Indian populations 14 including the south Indian population, 17 Indo-Mauritian population, 18 etc. Other fingertip features; 16 palm print ridge density 19 and footprint ridge density 20 were also studied in the past for sex differences. In the present study an attempt has been made to identify the sex of a person in a Central Indian (Marathi) population using thumbprint ridge density.…”

“…Those results are in agreement with many other studies. 6,8,9,14,15,17,19,20 In our study we found that the ridge density was higher in women compared to men. A number of previous studies similarly reported higher ridge densities in women.…”

El artesano de La Canal dels Avellaners (Edad de Bronce, Barcelona): análisis de huellas dactilares

“…Otras características interesantes como la anchura de las crestas se han investigado con menos asiduidad. En los últimos años, varios equipos de investigación se han interesado, precisamente, en aspectos como la densidad de la cresta, con el objetivo de inferir el sexo de los individuos en la población española (Gutiérrez-Redomero et al 2008), la población americana de ascendencia europea y africana (Acree 1999), la egipcia (Eshak et al 2012), la india (Nayak et al 2010a), la china y malaya (Nayak et al 2010b), la argentina (Rivaldería et al 2016), la filipina (Taduran et al 2015) o la del grupo indígena amerindio Mataco-Mataguayo (Gutiérrez-Redomero et al 2011). Estas investigaciones han puesto de manifiesto diferencias en la densidad de las crestas (y, por tanto, en su anchura) entre sexos (Ohler y Cummins 1942;Mundorff et al 2014), diferencia entre dedos y entre zonas de un mismo dedo .…”
