Question

When Clausen and colleagues grew genetically identical individuals of the yarrow plant at different elevations, the results are shown in the accompanying figure. This observation verifies that

1) yarrow plants mutate quickly when grown in different environments

2) the genotypes of yarrow plants has nothing to do with how tall these plants grow

3) yarrow plants grow taller at lower elevations and shorter at higher elevations regardless of their genotype

4) the genotypes of yarrow plants interacts with environmental influences to produce the phenotype

Answer 1

Yarrow plants grow taller at lower elevations and shorter at higher elevations, regardless of their genotype, as observed by Clausen and colleagues.

Step-by-step explanation:

The observation made by Clausen and colleagues verifies that the genotypes of yarrow plants interact with environmental influences to produce the phenotypes. This means that the genotypes of the plants play a role in determining how tall they grow in different elevations. The results show that yarrow plants grow taller at lower elevations and shorter at higher elevations, regardless of their genotype.
