The diploid chromosome number varies by organism and ranges from 10 to 50 chromosomes per cell. WebAbstract. Consistency of optimum chromosome spreading during harvest of cytogenetic specimens remains a major concern. We have tested the idea that a precise control of the drying rate (the time with which metaphase cells dry), as fixed cell suspension is placed on a slide or an in situ culture in last fixation, may be the answer. ordered search
