X Xarrow_forwardMatch the phases of meiosis with the correct description Metaphase I [ Choose ] [Choose ] Sister chromatids line up along the center of the cell. Cytokinesis produces four unique daughter cells, spindle dissolve, and the nuclear envelope reappears. Spindle fibers pull homologous pairs of chromosomes apart. Nuclear envelopes of daughter cells dissolve, and chromosomes condense. Spindle fibers pull sister chromatids apart. Homologous pairs of chromosomes line up at the center of the cell in tetrads. Cytokinesis produces two daughter cells, spindle dissolves, and nuclear envelope reappears. Nuclear envelope dissolves, DNA condenses and crossing over occurs.
