You crossed a red-flowered plant (gene symbol, r) to aplant that is dwarf (gene symbol, d) and peloria (gene symbol, p).All of the F1 plants are tall with red, normal stem flowers. Youcross an F1 plant back to the dwarf and peloria parent, and you seethe 543 progeny shown in the chart.

Dwarf, peloria stem, white 172

Tall, peloria stem, red 56
