Meiosis includes a recombination checkpoint that is analogous to the checkpoints in cell-cycle progression. Double-strand breaks in the DNA initiate recombination in meiosis.
 
  The broken end of a DNA molecule finds the corresponding sequence on a homologous chromosome and exchanges a chromosomal segment with its homolog, thereby repairing the break. Ongoing recombination sends a negative regulatory signal that prevents cells from entering meiotic division I.
  A. Mutations in several genes inactivate the recombination checkpoint. What do you predict will happen if a cell proceeds through meiotic division I before completing recombination?
  B. What will happen if a cell fails to initiate recombination and proceeds through meiotic division I? Meiotic division II?
