In the tomato, three genes are linked on the same chromosome. Tallis dominant to dwarf, skin that is smooth is dominant to skin that ispeachy, and fruit with a normal rounded tomato shape is dominantto oblate (flattened) shape. A plant that is true-breeding for thedominant traits was crossed to a dwarf plant with peachy skin andoblate fruit. The F1 plants were then testcrossed to dwarf plants withpeachy skin and oblate fruit. The following results were obtained: 151 tall, smooth, normal33 tall, smooth, oblate11 tall, peach, oblate2 tall, peach, normal155 dwarf, peach, oblate29 dwarf, peach, normal12 dwarf, smooth, normal0 dwarf, smooth, oblate Construct a genetic map that shows the order of these three genesand the distances between them?
