![]() Mendel’s study produced astonishing results and found very similar patterns of inheritance for all seven features he studied. ![]() Over eight years, Mendel studied pea traits one at a time and crossbred variants to systematically record how traits were passed on from one generation to the next: a mammoth task that involved approximately 28,000 pea plants. The relatively short growth period is another advantage, meaning there was not a long wait for the results. The pea flower is another useful feature of these plants, as it ensures that the flowers of the hybridised and parent plants are protected from any foreign pollen. seed shape – round or wrinkled plant height – tall or short). However, Austrian monk Gregor Mendel was unconvinced with traditional explanations of how traits were passed from one generation to another.īetween 18, Mendel decided to try and work out the principles of heredity himself, with the assistance of the humble garden pea ( Pisum sativum L.).Īmong the many species on which Mendel worked, he selected pea because the plants and seeds have a wide array of distinct features that occur in two easily identifiable forms (e.g. Heredity was poorly understood in general, and the concept of a gene did not exist at all. In the 19 th century, it was commonly believed that an organism’s traits were passed on to offspring in a blend of characteristics ‘donated’ by each parent.
