A triple-point testcross of a plant is used to determine the order of linked genes

A triple-point testcross of a plant is used to determine the order of linked genes g, t, and l. The wild-type parental phenotypes are green, tall, and leafy, represented by the triple heterozygote g+t+l+/gtl. The mutant plants are red, dwarf, and sparse, represented by the triple recessive genotype gtl/gtl. The least frequent phenotypes in the progeny of the testcross are red, tall, and leafy, and green, dwarf, and sparse. Based on the results of the testcross below, what is the genetic distance in map units between the genes g and l?
