Prophase 1 | chromosomes condense
homologs pair up
Recombination of alleles
chromosomes exchange DNA in crossing over |
Metaphase 1 | Random alignment of homologous chromosomes at equator
chromatids held at centromere |
Anaphase 1 | chromosomes separate moving to opposite poles |
Telophase 1 | Nuclear membranes reform and two cells ate formed each with N=2 chromosomes
spindle fibers disassemble |
Prophase 2 | There are two cells and DNA does not replicate again |
Metaphase 2 | individual chromosomes line up at equator |
Anaphase 2 | Chromatids split at centromere and are moved to opposite poles of the cell |
Telophase 2 | Nuclear membranes reform and there are 4 new haploid daughter cells |
Recombination | When information on chromosomes switch around |
