A) Chiasmata are randomly distributed along chromosomes.
B) All chromosome pairs have the same number of chiasmata.
C) A single chromosome pair always has the same number of chiasmata in every meiotic cell.
D) Chiasmata are spaced along a chromosome arm more regularly than would be expected by chance.
E) Chiasmata are spaced more irregularly along a chromosome arm than would be expected by chance.
