Sex-Chromatin Variations in Institutionalized Females

The maximum number of sex-chromatin bodies in any cell nucleus is one less than the number of X chromosomes in that nucleus. After the single-X nature of the sex-chromatin body was demonstrated [16], Lyon [10] proposed a hypothesis which postulated that only one X chromosome continues to be active in each mammalian cell, and that each sex-chromatin body is derived from one of the cell’s inactivated X chromosomes.
