Sexual Dimorphism in the Prenatal Digit Ratio (2D:4D)
TLDR
The 2D:4D ratio, thus, seems to increase after birth in both men and women, with the second digit growing faster than the fourth digit (positive allometric growth of digit two) and perhaps more so in women than in men.
Digit Ratio and Dental Caries: A Sexually Dimorphic Trait
  • P. VermaA. Hegde
  • Psychology
    International journal of clinical pediatric dentistry

TLDR
A positive correlation between digit ratio, taste, social behavior, and dental caries is states, which is thought to be predetermined with caries experience in children of age group 6 to 16 years.
Do risk and time preferences have biological roots
TLDR
It is found that there is no effect of the menstrual cycle (and thereby, of associated fluctuations in progesterone and estradiol levels) or of the digit ratio on either risk or time preferences.
Prenatal testosterone exposure and numerical competence in children and adults
The present thesis sought to investigate the potential relationship between the second to fourth finger ratio (2D:4D), as a somatic marker of prenatal testosterone exposure, and basic numerical…
A COMPONENT-BASED APPROACH TO HAND-BASED VERIFICATION AND IDENTIFICATION SYSTEM
TLDR
A component-based approach to hand-based verification and identification which improves both accuracy and robustness as well as ease of use due to avoiding pegs is investigated.
Morphological aspects of male and female hands.

TLDR
Digital and metacarpal formulae are morphological variables which may also have functional significance in the understanding of how certain hand forms may be ill-fitted for certain tasks.
Relative index finger length as a sex-influenced trait in man.
  • V. Phelps
  • Biology
    American journal of human genetics
  • 1952
TLDR
Although Kloepfer (1946) has suggested that the variations in relative index finger length may be hereditary, no attempt has been made to establish that the various formulas may be observed in fetuses.
Anthropometrical study of the second and fourth digit ratio of Andoni (Obolo) groups of Ijaw ethnic nationality in Nigeria
This study was carried out to document values of the 2 nd to 4 th digit ratio of Andoni (Obolo) group of Ijaw ethnic nationality. Seven hundred and two subjects between ages of 15 and 60 years were…
