 (krō′mə-tĭd)
n.
Either of the two daughter strands of a replicated chromosome that are joined by a single centromere and separate during cell division to become individual chromosomes.

chromatid

(ˈkrəʊmətɪd)
n
(Genetics) either of the two strands into which a chromosome divides during mitosis. They separate to form daughter chromosomes at anaphase

chro•ma•tid

(ˈkroʊ mə tɪd)

n.
either of two identical chromosomal strands into which a chromosome splits before cell division.
[1900; < Greek chrōmat- (see chromatin) + -id1]

chro·ma·tid

(krō′mə-tĭd)
Either of the two strands formed when a chromosome duplicates itself during cell division. The chromatids are joined together by a single centromere and later separate to become individual chromosomes. See more at meiosis, mitosis.

Triploidy owing to a non-disjunction event in meiosis 2 will have a preponderance of similar-sized alleles, as two similar sister chromatids separate during this process.
In this study, the author proposed that the non-repair of the chromosomes that had lost the telomeric region generates cycles of breakage-fusion-bridge, since there is the fusion of sister chromatids with no telomeres, transforming them into a chromosome with two centromeres.
Telophase###Sister chromatids are forming scattered
SCEs represent symmetrical exchanges of replicated DNA between sister chromatids.
Objective: Following their synthesis during DNA replication, sister chromatids remain paired by the cohesin complex, which forms the basis for their faithful segregation during cell division.
Scientists from Japan, Europe, and the US discuss the history of mitosis research and the model systems that have played a key role; how threads are produced through chromosome condensation; how sister chromatids attach to each other and to the spindle apparatus; how the spindle microtubules nucleate, elongate, pause, and shrink; how kinetochores and centrosomes serve as anchor and control points; the biochemical elements that coordinate the main regulatory stages of entry into mitosis, sister chromatid separation, and mitotic exit; how cells can mis-segregate and unbalance the genome; the cellular changes that occur during cytokinesis; and the differences between mitosis and meiosis.
Seven markers revealed that the fetus inherited with two maternal alleles and one paternal allele, which prove maternal inheritance of triploidy that occurred due to failure of homologous chromosome or sister chromatids to separate properly in meiosis-I.
mechanism because gametes contain non-sister chromatids from the
The centromere is the part of a chromosome that links sister chromatids.
The damaged chromosomes, in the form of acentric chromatids or chromosome fragments, lag behind in anaphase when centric elements move towards the spindle poles.
SCE assay is a short-term test for the detection of reciprocal exchanges of DNA between two sister chromatids of a duplicating chromosome.
3] SCE arises by reciprocal DNA interchanges between sister chromatids during replication of damaged DNA templates.
