In the tubular flowers of foxgloves, wild-type coloration is redwhile a mutation called white produces white flowers. Anothermutation, called peloria, causes the flowers at the apex of thestem to be huge. Yet another mutation, called dwarf, affects stemlength. 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.

Red, tall, normal stem 162
Dwarf, normal stem, white 51
1) Which alleles are dominant?
2) What were the genotypes of the parents in the originalcross?
3) Draw a map showing the linkage relationships of these threeloci(R, D, P)
