Mitosis vs. meiosis Match each description with the appropriate type of cell division.

Question: Mitosis vs. meiosis Match each description with the appropriate type of cell division.

Solution:

Mitosis :

  • Homologous chromosomes behave independently of each other.
  • The new cells produced are genetically identical to each other and to the original cell.
  • During the first nuclear division, sister chromatids separate and move to opposite poles.
  • DNA replication is followed by a single nuclear division.

Meiosis:

  • There are 2 nuclear divisions with no DNA replication between them.
  • During the first nuclear division,homologous chromosomes separate and move to opposite poles.
  • Independent assortment of maternal and paternal chromosomes.
  • Crossing over occurs.
  • Synapsis occurs.
  • During the first nuclear division, sister kinetochores fuse and are attached to the same pole.
  • The chromosome number is reduced from 2 sets to 1 set.
  • During the first nuclear division, chromosomes line up along the equatorial plate in pairs.

Neither mitosis nor meiosis:

  • Nuclear division occurs twice but cytokinesis occurs only once.

Both mitosis and meiosis :

  • Chromosomes condense before they attach to the spindle.
