WebMitotic abnormality is associated with the onset of aneuploidy, recognized as one of the hallmarks of cancer. The maintenance of a normal ploidy status depends largely on the fidelity of chromosomal division during mitosis. The fidelity of this process is controlled by three main mechanisms: spindle assembly checkpoint (SAC), the amplification cycle of … Webpolyploid mitosis will show normal chromosomes (2-chromatid chromosomes or «mon ochromosomes»); in case of endoreduplication (polyteny) the first mitosis will show diplochromosomes or quadruplochromosomes (exceptionally polytene chromosomes of higher order) 10 • 12 • 33 • In non-dividing tissues, ploidy levels can also be determined by liters of normal saline https://frmgov.org
