What is it called when sister chromatids fail to separate during meiosis?

In my studies I have not thus far seen any instances in which sister chromatids did not separate in Anaphase, but there are instances where chromatids do not evenly cleave from one another and there is more genetic material in one gamete than another of the gametes, and the other two are "normal". I will illustrate this mathematically : N+1(24) , N-1(22), N(23), N(23).
This uneven split is called non-disjunction which can happen in Anaphase 1 or 2 in the gamete producing cell division known as Meiosis
One may familiar to one of the consequences of non-disjunction if he/she had heard of Down syndrome. Individuals with DS have 47 chromosomes. This is a condition called Trisomy where the 21st pair of sex determining X chromosomes has an extra X.
However, in many cases non-disjuction may have zero effect on individual. It is completley dependent on what pair of chromosomes has an extra, or one less chromosome that determines the outcome of the cells development.
I hope that helps somewhat.

Which is the failure to segregate during meiosis?
Failure of the chromatids to separate during anaphase onr or two of meiosis
Do chromatids separate during telophase?
chromatids separate during anaphase.anaphase is when the spindle fibers start pulling the "sister" chromatids apart
What happens in meiosis during anaphase I?
The chromosomes split equally and move to the opposite sides of the cell.
What division of meiosis splits chromosomes?
In anaphase I of meiosis, the homologous pairs of chromosomes separate. Due to DNA replication and crossing over during prophase I, these chromosomes consist of a pair of non-identical sister chromatids. During anaphase II of meiosis, the sister chromatids separate into individual chromosomes.
The chromatids detach from one another and become visibly separate chromosomes during?
The chromatids detach from one another and become visibly separate chromosomes during anaphase. Chromatids that are attached at the centromere are called sister kind of chromatids.
When during meiosis do sister chroamtids separate?
Sister chromatids separate during anaphase II of meiosis.
What are the centromeres slip and the chromatids separate?
what are the centromeres spit and the chromatids separate
Which is the failure to segregate during meiosis?
Failure of the chromatids to separate during anaphase onr or two of meiosis
Chromatins separate during?
Chromatids separate during cell division ie anaphase of mitosis and anaphase 2 of meiosis.
Do chromatids separate during telophase?
chromatids separate during anaphase.anaphase is when the spindle fibers start pulling the "sister" chromatids apart
What happens in meiosis during anaphase I?
The chromosomes split equally and move to the opposite sides of the cell.
What division of meiosis splits chromosomes?
In anaphase I of meiosis, the homologous pairs of chromosomes separate. Due to DNA replication and crossing over during prophase I, these chromosomes consist of a pair of non-identical sister chromatids. During anaphase II of meiosis, the sister chromatids separate into individual chromosomes.
Does meiosis ll separate chromatids into opposite poles of the Cell?
Yes, during anaphase II.
Chromatids line up along the equator?
The chromatids line up at the equator of the cell during the metaphase of meiosis. After which the chromatids separate to form individual chromosomes.
The chromosomes separate and move in opposite directions during?
IN Mitosis, the Siter chromatids separate in anaphase. IN Meiosis, the tetrads separats in anaphase I and the siter chromatids separates in anaphase II
What separates during meiosis 2?
In Meiosis, Anaphase 2 sister chromatids (individual strands) separate and one of each duplicate goes to each side of the cell.
During which phase of meiosis will the chromosomes appear as packets of four chromatids?
chromosomes appear as packets of four chromatids during anaphase. This is when the chromatids start to move and separate in preparation of the creation of four cells.
