Abstract

The strand relationships of adjacent pairs of chiasmata have been examined in differentially stained meiotic bivalents following in vivo BrdU substitution and FPG staining. A test for chromatid interference is described, based on comparisons of the observed numbers of various combinations of “hidden” and “visible” crossover exchanges with the numbers expected assuming no chromatid interference. A comparison based on 67 pairs of chiasmata from Locusta migratoria indicates no evidence for chromatid interference in this material.
