Gregor Mendel was an Austrian-Hungarian monk who is regarded to be the father of genetics. Mendel was born in poverty and was often believed to suffer from autism. He studied mathematics and physics at university, but subsequently dropped out as he could not fund his studies. He joined amonastery to escape a life of poverty. He loved to collect biological specimens and from this he noticed the different traits that animals and plants possessed. Curiosity led him to experiment with plants in a greenhouse at the monastery, as experiments using animals was forbidden. He collected pure bred pea plants of different colours (green and yellow) and bred them together. He collected the seeds and planted them, noting that all the plants of this second generation produced green peas. He cross bred this second generation of peas and replanted the seeds. Surprisingly, of the third generation, most of the peas produced were green, and a few plants produced yellow peas. From this he deduced that the pea colour was determined by a gene that had different forms, called alleles. Using mathematics he found that the ratio of green peas to yellow peas came to 9:3:3:1, now called the classical Mendelian ratio. This work led to the development of the theory of genetics and how some alleles were dominant over the other and thus deduces the phenotype of the organism in question.
