  • Homologous chromosomes (one from each parent) line up randomly at the equator of the cell.

  • The orientation of each homologous pair is independent of the orientation of other pairs.

  • This leads to a huge number of possible combinations of chromosomes in the gametes. For a species with nchromosome pairs, there are 2ⁿ possible combinations.
