In the tomato, three genes are linked on the same chromosome. Tall is dominant to dwarf, skin that is smooth is dominant to skin that is peachy, and fruit with a normal rounded tomato shape is dominant to flattened, or oblate shape. A plant that is true-breeding for the dominant traits was crossed to a dwarf plant with peachy skin and oblate fruit. The F plants were then testcrossed to dwarf plants with peachy skin and oblate fruit. The following results were obtained:
151 tall, smooth, normal
33 tall, smooth, oblate
11 tall, peach, oblate 2 tall, peach, normal
155 dwarf, peach, oblate 29 dwarf, peach, normal
12 dwarf, smooth, normal
0 dwarf, smooth, oblate
Construct a genetic map that describes the order of these three genes and the distances between them.
