Abstract

a<p><i>Sticky chromosomes</i> refer to the tendency of chromosome arms or entire chromosomes to stick together.</p>b<p><i>Chromatin bridges</i> occur in mitosis when the telomeres of sister chromatids fuse together and fail to completely segregate into their respective daughter cells. <sup>c</sup><i>Vagrant forms</i> refer to chromosomal formations different from the normal formation during mitosis.</p>d<p><i>Binucleated cells</i> have more than one nucleus. <sup>e</sup><i>Multipolar mitosis</i> occurs when the chromosomal material is pulled to more than two poles, resulting in the formation of a corresponding number of nuclei. <sup>f</sup><i>Chromosomal fragments</i> refer to fragments of a chromosome that may be lacking a centromere and so is often lost when the cell divide.</p
