متن کاملIs CAG sequence length in the androgen receptor gene correlated with finger-length ratio?
Manning, Bundred, Newton, and Flanagan reported a significant correlation of .29 in a sample of 50 British males between the length of a repeated sequence on the androgen receptor gene and 2D:4D finger-length ratio on the right hand. We report a 2nd failure to replicate this result. Ours was a sample of 182 Australian male twins studied for other purposes, for whom both measures were available....

In addition the relationship between the fourth and fifth digits, i.e. the little finger and ring finger, and these two constructs was a...

متن کاملFinger length ratio (2D:4D) and sex differences in aggression during a simulated war game

We also investigated whether 2D:4D mediated the tendency for men to attack more than women and whether personality dimensions previously associated with sex differences in aggression or hostility (social domina...
