PROPHASE II
A spindle apparatus forms.
Chromosomes composed of two chromatids associated at the centromere
METAPHASE II
Chromosomes are positioned on the metaphase plate as in mitosis.
Crossing over in meiosis
Two sister chromatids of each chromosome are not genetically identical
ANAPHASE II
Centromeres divide or replicate to allow separation of sister chromatids;
The chromatids move toward opposite poles as individual chromosomes.
ANAPHASE II
Add:
Direction of chromosome movement in Anaphase I at right angles to that in Anaphase II.
TELOPHASE II AND CYTOKINESIS
Nuclei form
Chromosomes begin decondensing
Cytokinesis occurs
4 daughter haploid cells
Each genetically distinct from the other
It’s Video Time!
