noting that selection was only effective when based on genetic (genotype) rather than environmental (phenotype) differences.
With this information, we can conclude that Although Mendel conducted his experiments with pea plants in the mid-1800s, it was not until 1909 that Johannsen became the first person to describe Mendel's individual units of heredity. He called them genes.
