2 Figure 1 Obligate Crossovers and Crossover Interference
Diplotene of male meiosis in the locust Schistocerca gregaria (2n = 22 + X) showing 11 autosomal bivalents and the univalent X chromosome. Multiple chiasmata (crossovers) in the longer bivalents are spaced well apart (long arrows), whereas the smallest chromosomes regularly achieve a single obligate chiasma (short arrows).
