Best answer: What is separated in anaphase II?

What separated during anaphase 2?

In anaphase II, the sister chromatids separate and are pulled towards opposite poles of the cell. In telophase II, nuclear membranes form around each set of chromosomes, and the chromosomes decondense.

What component get separated in the anaphase I vs anaphase II?

Anaphase1:Homologouschromosomesareseparatedduringanaphase1. … Anaphase2:Twosisterchromatidsareseparatedbysplittingthecentromere.

What happens at anaphase II?

Anaphase II: The chromatids split at the centromere and migrate along the spindle fibers to opposite poles. Telophase II: The cells pinch in the center and divide again. The final outcome is four cells, each with half of the genetic material found in the original. In the case of males, each cell becomes a sperm.

What is separated in anaphase?

During anaphase, each pair of chromosomes is separated into two identical, independent chromosomes. The chromosomes are separated by a structure called the mitotic spindle. … The separated chromosomes are then pulled by the spindle to opposite poles of the cell.

What is the difference between anaphase 1 and anaphase 2?

Anaphase 1 and anaphase 2 are two phases in the meiotic division of cells which produces gametes during the sexual reproduction. The main difference between anaphase 1 and 2 is that homologous chromosomes are separated during anaphase 1 whereas sister chromatids are separated during anaphase 2.

What happens during anaphase II of meiosis quizlet?

What happens during anaphase II of meiosis? Sister chromatids separate from each other and migrate to opposite ends of the cell. … Homologous chromosomes separate but sister chromatids remain joined at their centromeres. Meiosis results in genetic variation among its product cells.

What is happening to the chromosomes sister chromatids during anaphase II?

During anaphase II, the third step of meiosis II, the sister chromatids of each chromosome separate and move toward opposite poles. Once they are no longer connected, the former chromatids are called unreplicated chromosomes.

How does segregation happen during anaphase 2?

There are two ways in which non-disjunction can occur: 1) both homologous chromosomes migrate together to one pole instead of separating to opposite poles in Anaphase I or 2) sister chromatids fail to separate properly and both sister chromatids move together to one pole instead of to opposite poles in Anaphase II.
