The cytogenetic analysis of single cells, such as oocytes and polar bodies, is extremely challenging. The main problem is low probability of obtaining a metaphase preparation in which all of the chromosomes are sufficiently well spread to permit accurate analysis (no overlapping chromosomes, no chromosomes lost). As a result, a high proportion of the oocytes subjected to cytogenetic analysis are not suitable for traditional chromosome banding studies or for molecular cytogenetic methods such ...Expand abstract
