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?

A cross between two cucumber plants, both with normal leaves, results in 75% offspring with normal leaves and 25% offspring with crinkled leaves. A. Predict the genotypes of the parent plants. (2 points) B.  Explain your reasoning. Include a Punnett square (use the “insert chart” option) that supports your prediction (3 points).
