Gregor Johann Mendel(1822-1884) is an Augustinian friar and became the father of Modern Genetics. Mendel presented his paper Versuche uber Pflanzenhybriden (Experiment on Plant Hybridization) at two meetings of the Natural History Society of Brunn in Moravia in 1865. Mendel also discovered the fundamental principles of Genetics by breeding garden peas. When ma'am ruby asked a question about mendel. Why Mendel used Garden pea for his experiments? Here's the answer,

Mendel’s experimental use of the garden pea, Pisum sativum was evidently not an accident but the result of long careful thought. First, pollination could easily be controlled in this plant. Normally, the pea plant was self- fertilizing and, therefore, the use of Mendel’s main techniques, ‘selfing’, presented no difficulties.
