In Drosophila, three loci, Aristapedia (Ar), Dichaete wings (D), and Radius incompletus (Ri) are all located on chromosome III. Ar is located at position 47.5, D at position 41, and Ri at position 47. Would you expect chromosomal interference to reduce the number of double crossovers during gametes formation?
