Answer:
Mountain lands provide a scattered but diverse array of habitats in which a large range of plants and animals can be found. At higher altitudes harsh environmental conditions generally prevail, and a treeless alpine vegetation, upon which the present account is focused, is supported. Lower slopes commonly are covered by montane forests. At even lower levels mountain lands grade into other types of landform and vegetation—e.g., tropical or temperate forest, savanna, scrubland, desert, or tundra.
The largest and highest area of mountain lands occurs in the Himalaya-Tibet region; the longest nearly continuous mountain range is that along the west coast of the Americas from Alaska in the north to Chile in the south. Other particularly significant areas of mountain lands include those in Europe (Alps, Pyrenees), Asia (Caucasus, Urals), New Guinea, New Zealand, and East Africa. The worldwide distribution of mountain lands is shown in Figure 1.

This sounds like a test cross. Because P is dominant, the purple flower could have a genotype of Pp or PP. If all of the offspring of the test cross are purple, then the purple flower has genotype PP. If half of the offspring of the test cross have purple and half have white, then the purple parental flower's genotype is Pp.
