During anaphasic movement of chromosome
Chromatin bridge is a mitotic occurrence that forms when telomeres of sister chromatids fuse together and fail to completely segregate into their respective daughter cells. Because this event is most prevalent during anaphase, the term anaphase bridge is often used as a substitute. After the formation of individual daughter cells, the DNA bridge connecting homologous chromosomes remain… WebIn anaphasic movement of chromosomes, the centromeres lead the path while the arms trail behind. As a result the anaphasic chromosomes appear V., L, J- and I-shaped. The shapes are formed respectively in metacentric, submetacentric, acrocentric and telocentric chromosomes.

ALTERNATE SEGREGATION:- The alternate chromosomes of the ring go to the same pole; the normal chromosomes on one pole and the translocation chromosomes on the other pole. WebAnaphase is the stage of mitosis or meiosis when chromosomes split and the sister chromatids move to opposite poles of the cell. During anaphase II, the centromeres …
WebDeficiency is due to loss of a part of chromosome. If the lost part of chromosome does not have a centromere, it is left behind during anaphasic movement. This part of chromosome, thus gets excluded from the newly formed nucleus. Such a condition is generally lethal for an organism. Smaller deficiencies, present in heterozygous condition …
