Nondisjunction occurs when chromosomes fail to separate during meiosis, resulting in gametes with an abnormal number of chromosomes. In this case, an XXX female would result from the failure of the X chromosome to separate from one of the pairs during meiosis in the mother's egg cell. Therefore, the most likely scenario for nondisjunction resulting in an XXX female is during egg formation in the mother.
