· Bridges explained these results by proposing that the exceptional F1 flies were the result of abnormal X chromosome behavior during meiosis in the females of the P generation. Normally the X chromosome in females separates or disjoin during gametogenesis but Occasionally they might fail to separate producing an egg with two X chromosomes (diplo-X) or an egg with no X chromosome at all

Chromosome breaks can lead to "breakage–fusion–bridge" cycles in which broken ends from different chromatids or chromosomes fuse producing a dicentric chromosome. These chromosomes may thus be pulled in opposite directions during mitosis and broken as a result.
