Homologous chromosomes are pulled to opposite sides of the cell
Anaphase II
Two new haploid cells are produced, each containing chromosomes with sister chromatids
Tetrads line up in the middle of the cell
Prophase II
A total of four haploid cells are produced, each containing chromosomes but no chromatids
Interphase
Anaphase I
Crossing Over
Metaphase II
DNA replicates, creating sister chromatids
Random chance decides whether a chromosome is pulled to one side of a cell or the other
Metaphase I
Independent Assortment
Telophase I (& Cytokinesis)
Individual chromosomes line up in the middle of the cell
Genetic information is "traded" between the chromatids of homologous chromosomes
Individual chromosomes attach to spindle fibers ; not much else happens
Sister chromatids are pulled to opposite sides of the cell
Telophase II (& Cytokinesis)
Prophase I
Homologous chromosomes form tetrads; Crossing over occurs
