Among the dichotomous (present/absent:absent/present) ossinication sequences individually ascertained in 3059 boys and girls with at least one but not more than 27 ossification centers of the hand and wrist, 54 such sequences exhibit statistically‐significant sex differences in frequency, 32 of them at the 1% confidence level or better. Analyzed by regions (rows and rays, epiphyses and round bones), ten centers, primarily distals and those of the first digit, account for the majority of the significant sex differences.
