is to discriminate functions for sex determination in a subjected sample of the
Egyptian population using the morphology of metacarpals and phalanges for
gender comparison. Furthermore, the measurements discussed in this study will
aid in predicting the differentiation independently and guaranteeing sex
determination in the subjected population individually. <b>Methods:</b> Forty
measurements were taken from the right metacarpals and phalangeal bones of 100
subjects, whose ages ranged from 19 to 60. Moreover, the measurements of nine
metacarpals and four phalangeal bones were used for sex discrimination in each
sample population. <b>Results:</b> Males had significantly greater mean values
(</span><span style=\"font-size:10.0pt;font-family:&quot;\">P</span><span style=\"font-size:10.0pt;font-family:&quot;\"> &lt; 0.05) for the lengths of the metacarpals and
the proximal phalangeal bones of all right-hand fingers than females. <a name=\"_Hlk93495261\"></a>The cut-off value and the accuracy percentage for precise
sex classification of males and females using individual and grouped bones
showed that a value higher than the marking point classified an individual as
male and that a lower value suggested female. Besides, the multiple
stepwise discriminant functional analysis of the most predictable internal
variables of the metacarpals revealed a cross-validated sex classification
accuracy of 100%. In contrast, the most predictable internal variables of the
phalanges showed a cross-validated sex classification accuracy of 93%. <b>Conclusion:</b> The results revealed a new forensic suggestion for the determination of sex
based on the measurements of the metacarpals and the phalanges. Moreover, various
discriminant equations were applied for the declaration of this conceivable
recommendation.
