Unit 11


Prophase I Each chromosome comes near its replicated chromosome pair. Nucleus dissolves at this stage. Crossing Over (exchange of genetic material) occurs at this phase.
Metaphase I The pairs of homologous chromosomes line up in the center of the cell. The centromere of each chromatid pair attaches to one spindle fibre.
Meiosis II Dyads are broken down into monads
Anaphase I Homologous chromosomes are pulled to opposite ends of the cell. Note that chromatids do not separate - each duplicated chromosome still has two chromatids.
Telophase I The cytoplasm divides and two new cells form. Each new cell has one duplicated chromosome from each similar pair. 2 diploid cells have been produced
Prophase II The duplicated chromosomes and spindle fibers reappear in each new cell.
Metaphase II The duplicated chromosomes move to the centre of the cell. Each centromere attaches to two spindle fibres instead of one.
Anaphase II The centromere divides. The chromatids seperate and move to opposite ends of the cell. Each chromatid is now an individual chromosome.
Telophase II The spindle fibres disappear, and a nuclear membrane forms around each set of chromosomes. 4 haploid Cells are produced
