Questions and Answers

During meiosis, what happens in Telophase I?

  • Two daughter cells are formed with each cell having the half number of chromosomes. (correct)
  • Chromosomes align at the equatorial plate.
  • Homologous pairs separate with sister chromatids remaining together.
  • Nuclear membrane and nucleoli completely disappear.

What occurs during Anaphase II of meiosis?

  • Nuclear membrane and nucleoli completely disappear.
