reciprocal cross 147) A) Assuming these are not endangered plants and you are not in a protected area, obtain several specimens from each location. Plant seeds of both types of plants in both low- and high-altitude locations. Observe the offspring.

If the offspring look short and bushy with small fragrant, bright purple flowers in the lower altitude, but tall and sparse with larger flowers of the same colour and fragrance in the higher altitude, then the differences are d to environmental influences.
