In 1856 Mendel began his hybridization experiments in plant with garden peas in the monastery
garden.Similar work had already been done by contemporary botanists but the significant
features of all these experiments had been overlooked because the investigators made overall
observations of all inherited characters instead of collecting and analyzing data in a systematic,
mathematical way. This is how Mendel achieved what his predecessors could not.
1)First of all he concentrated his attention on a single character in his experiments on inheritance.
2)He kept accurate pedigree records for each plant.
3)He counted the different kinds of plants resulting from each cross.
4)He analysed his data mathematically.
5)Mendel’s success is in part also attributed to his choice of material. The garden pea
(Pisum sativum) used in his experiments has certain advantages:

(Pisum sativum) used in his experiments has certain advantages:
- It is an easily growing.
- It isnaturally self fertilising plant.
- It is well suited for artificial cross pollination therefore hybridisation (crossing of two different varieties) is easily accomplished.
- It shows pairs ofcontrasting characters which do not blend to produce intermediate types and can be tracedthrough successive generations without confusion.
