What does not occur during anaphase?
During anaphase, sister chromatids (or homologous chromosomes for meiosis I), will separate and move to opposite poles of the cell, pulled by microtubules. In nondisjunction, the separation fails to occur causing both sister chromatids or homologous chromosomes to be pulled to one pole of the cell.
What events occur during anaphase?
In anaphase, the sister chromatids separate from each other and are pulled towards opposite ends of the cell. The protein “glue” that holds the sister chromatids together is broken down, allowing them to separate. Each is now its own chromosome. The chromosomes of each pair are pulled towards opposite ends of the cell.
Which of the following must occur during anaphase?
Which of the following must occur during anaphase 1? Meiosis specific cohesion must be removed from chromosome arms, but not from sister centromeres.
Which of the following does not occur during telophase?

Which does not occur in meiosis quizlet?
Which does NOT occur in meiosis? … They undergo “endomitosis,” in which one extra chromosome replication results in a tetraploid cell before meiosis begins; normal female 2n offspring result without fertilization.
Which does not occur in prophase?
