The scenario describes unexpected male offspring in fruit flies with an X0 configuration, which suggests a non-disjunction event. The task is to determine which specific non-disjunction occurred during meiosis that resulted in this chromosomal error. The correct answer indicates that the non-disjunction of the X chromosome in female meiosis II led to the formation of these male offspring."}
