A plant species shows several morphological variations in response to altitudinal gradient. When grown under similar conditions of growth, the morphological variations disappear, and all the variants have common morphology. What are these variants called?

Answers (1)

Ans: The variants that occur due to the morphology are called biotypes. The biotypes have a similar genetic structure, but they have different morphology because the abiotic factors like pH of the soil, temperature, rainfall, etc. change the morphology of the plants. This change is an abiotic factor is observed due to the difference in the altitude gradient.
