CellCyclesIntroduction
The onion root tip and the whitefish blastula remain as the standard introduction to the study of mitosis. The onion has easily observable chromosomes, and the whitefish has one of the clearest views of the spindle apparatus. The testis of the grasshopper and the developing zygote of the roundworm Ascaris are the traditional materials used for viewing the various stages of meiosis.In a single longitudinal section of ......阅读全文
