LINEAR PLUSES. “In the reductional division of meiosis, the homologous chromosomes are held together by their chiasmata where recombination has generated a crossover between homologous chromatids. A single meiotic crossover (or any uneven number of crossovers) generates a dicentric circle, which will lead to non-disjunction of the homologs. As this problem is circumvented with linear chromosomes, linearization may have provided a selective advantage.”
