Identify the stages of Meiosis where each event happens*8 pointsP-I M-i A-I T-I P-II M-II A-II T-IIChromosomes decondense, nuclear membrane may reform, cell divides (cytokinesis) to form two haploid daughter cells Spindle fibers contract and separate the sister chromatids, chromatids (now called chromosomes)move to opposite poles Chromosomes condense, nuclear membrane dissolves, homologous chromosomes form bivalents, crossing over occurs Spindle fibers from opposing centrosomes attach to chromosomes (at centromere) and align them along the cell equator. Spindle fibers contract and split the bivalent, homologous chromosomes move to opposite poles of the cell Spindle fibers from opposing centrosomes connect to bivalents (at centromeres) and align them along the middle of the cell Chromosomes condense, nuclear membrane dissolves, centrosomes move to opposite poles (perpendicular to before) Chromosomes decondense, nuclear membrane reforms, cells divide (cytokinesis) to form four haploid daughter cells Chromosomes decondense, nuclear membrane may reform, cell divides (cytokinesis) to form two haploid daughter cells Spindle fibers contract and separate the sister chromatids, chromatids (now called chromosomes)move to opposite poles Chromosomes condense, nuclear membrane dissolves, homologous chromosomes form bivalents, crossing over occurs Spindle fibers from opposing centrosomes attach to chromosomes (at centromere) and align them along the cell equator.
