**Step-by-Step Solution:** 1. **Introduction to Morgan's Experiment:** Thomas Hunt Morgan conducted experiments with Drosophila melanogaster (fruit flies) to study inheritance patterns. He specifically focused on dihybrid crosses, which involve two traits. 2. **Description of Traits:** In his experiments, Morgan used Drosophila with two traits: body color (yellow vs. brown) and eye color (white vs. red). He crossed a yellow-bodied white-eyed female with a brown-bodied red-eyed male. ...
