Phases of Meiosis

PART I: Phases of Meiosis Review: Write the name of the phase that corresponds to the description. Include at least one of
the descriptions in your answer.
Name of Phase
Homologous chromosomes pair up and form tetrad, Crossing-over occurs
Spindle fibers move homologous chromosomes to opposite sides
Nuclear membrane reforms, cytoplasm divides, 4 daughter cells formed
Chromosomes line up along equator, not in homologous pairs
New spindle fibers form
Chromatids separate
Homologs line up alone equator
Cytoplasm divides, 2 daughter cells are formed
PART II: Determine the correct order that these cells should go in. Write the corresponding numbers in the correct order on
your own sheet of paper.
1 Diploid Germ Cell___  ___  ___  ___  ___  ___  ___  ___  4 Haploid Gametes
