Answer:
To perform the same experiment as done by Mendel, the first and foremost condition would be the similarity with Mendel's actual experiment. The experiment done by Mendel demonstrates the existence of two alleles monitoring a single trait.
Mendel used pea plants in order to study the inheritance of traits. He utilized plants that exhibit only two alleles for a specific trait. Thus, in order to study the plant as Mendel did, one should opt for the plant that exhibits two alleles for a specific trait.
