The accompanying diagrams show two nonhomologous chromosomes, each containing a copy of a transposable element (shaded), that can be oriented either (a) in the same direction or (b) in opposite directions with respect to the centromere. For clarity, the length of the transposable element is greatly exaggerated relative to the length of the chromosome. (In reality, the average transposable element in Drosophila is about 0.01 percent of the length of a chromosome.) Draw diagrams illustrating the consequences of ectopic recombination between the transposable elements.
