Why was Mendel's approach to the study of heredity so successful? Mendel's approach to the study of heredity was so successful for many reasons. First, his choice in using the garden pea for his experiment was very advantageous, because these plants varied in height and in the appearance of their flowers, seeds, and pods. The pea plants were also very easily crossed, which worked in Mendel's favor, as he was able to manipulate the crosses and study the results easily. Mendel also began his e...
