Rank the steps of meiosis I in the order in which they occur, beginning with the first phase at the top.

Meiosis steps

The first phase of meiosis, during which crossing-over occurs, is I.

Arrange the following events in the proper order in which they occur during meiosis I.1 = Separation of homologous chromosomes2 = Coming together of homologous chromosomes3 = Crossing-over4 = Random orientation of homologous chromosomes at cell equatorMultiple Choice2, 3, 4, 12, 3, 1, 42, 4, 3, 11, 2, 3, 41, 3, 2, 4

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.
