Which statement best describes the process of crossing over? Homologous chromosomes pair up, and non-sister chromatids exchange genetic material.   Homologous chromatids pair up, and non-sister chromosomes exchange genetic material.

Which of the following are differences between mitosis and meiosis I? CHOOSE ALL THAT APPLY. A) Crossing over occurs during meiosis I but not during mitosis B) DNA replication takes place prior to mitosis, but not before meiosis I C) Sister chromatids separate in mitosis, and homologs separate in meiosis I D) Only meiosis I results in daughter cells that contain identical genetic information E) Meiosis I results in two daughter cells, while mitosis results in four daughter cells

Match 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.
