A total of 173 chromosomes were detected in my room, of which 6 were abnormal in karyotype, with a prevalence of 3.4%. There were 7 cases with variation of body region, accounting for 4.1%, and 30 ~ 50 cases with cleavage phase were analyzed with normal karyotype. It was found that only a single cell staining structure of 20 cases of distortion, including translocation, inversion, deletion, dicentric, the incidence was 11.6%.
