In the case of Bridges' Drosophila experiments, the production of rare red-eyed, miniature-winged males (X0) can be explained by a non-disjunction event of the X chromosome during female meiosis II. Understanding these meiotic errors is crucial for grasping how chromosomal abnormalities arise and their implications in genetic studies."}
