What are the chances of a second miscarriage due to chromosome abnormality?

Dependsonabnormality: Actually depends on where the abnormality came from (parent or not). If it is pre-existing in either parent, chances of recurrence can be as high as 100% in a fusion chromosome between the X chromosome and a non-X chromosome. If it is a new anomaly, chance are almost background, although seeing something once always raises the possibility of seeing it, or something like it, again. Can't generalize
