Original: Apr 27, Gregor Mendel was an Austrian monk who discovered the basic principles of heredity through experiments in his garden. Synopsis Gregor Mendel, known as the "father of modern genetics," was born in Austria in His experiments showed that the inheritance of certain traits in pea plants follows particular patterns, subsequently becoming the foundation of modern genetics and leading to the study of heredity.

He spent his early youth in that rural setting, until age 11, when a local schoolmaster who was impressed with his aptitude for learning recommended that he be sent to secondary school in Troppau to continue his education. The move was a financial strain on his family, and often a difficult experience for Mendel, but he excelled in his studies, and in , he graduated from the school with honors. There, he again distinguished himself academically, particularly in the subjects of physics and math, and tutored in his spare time to make ends meet.

Despite suffering from deep bouts of depression that, more than once, caused him to temporarily abandon his studies, Mendel graduated from the program in That same year, against the wishes of his father, who expected him to take over the family farm, Mendel began studying to be a monk: He joined the Augustinian order at the St. Thomas Monastery in Brno, and was given the name Gregor. In , when his work in the community in Brno exhausted him to the point of illness, Mendel was sent to fill a temporary teaching position in Znaim.

While there, Mendel studied mathematics and physics under Christian Doppler, after whom the Doppler effect of wave frequency is named; he studied botany under Franz Unger, who had begun using a microscope in his studies, and who was a proponent of a pre-Darwinian version of evolutionary theory. In , upon completing his studies at the University of Vienna, Mendel returned to the monastery in Brno and was given a teaching position at a secondary school, where he would stay for more than a decade.

It was during this time that he began the experiments for which he is best known. Experiments and Theories Around , Mendel began to research the transmission of hereditary traits in plant hybrids. Mendel chose to use peas for his experiments due to their many distinct varieties, and because offspring could be quickly and easily produced. He cross-fertilized pea plants that had clearly opposite characteristics—tall with short, smooth with wrinkled, those containing green seeds with those containing yellow seeds, etc.

He also proposed that this heredity followed basic statistical laws. In , Mendel delivered two lectures on his findings to the Natural Science Society in Brno, who published the results of his studies in their journal the following year, under the title Experiments on Plant Hybrids. Mendel did little to promote his work, however, and the few references to his work from that time period indicated that much of it had been misunderstood.

It was generally thought that Mendel had shown only what was already commonly known at the time—that hybrids eventually revert to their original form.

The importance of variability and its evolutionary implications were largely overlooked. Of course, his system eventually proved to be of general application and is one of the foundational principles of biology.

Later Life and Legacy In , Mendel was elected abbot of the school where he had been teaching for the previous 14 years, and both his resulting administrative duties and his gradually failing eyesight kept him from continuing any extensive scientific work.

He traveled little during this time, and was further isolated from his contemporaries as the result of his public opposition to an taxation law that increased the tax on the monasteries to cover Church expenses. Gregor Mendel died on January 6, , at the age of His work, however, was still largely unknown. Even then, however, his work was often marginalized by Darwinians, who claimed that his findings were irrelevant to a theory of evolution.

Top Questions Who was Gregor Mendel? Gregor Mendel was an Austrian scientist, teacher, and Augustinian prelate who lived in the s. He experimented on garden pea hybrids while living at a monastery and is known as the father of modern genetics. Why is Gregor Mendel famous? Through his careful breeding of garden peas, Gregor Mendel discovered the basic principles of heredity and laid the mathematical foundation of the science of genetics. He formulated several basic genetic laws, including the law of segregation, the law of dominance, and the law of independent assortment, in what became known as Mendelian inheritance.

They lived and worked on a farm which had been owned by the Mendel family for at least years [6] the house where Mendel was born is now a museum devoted to Mendel [7]. During his childhood, Mendel worked as a gardener and studied beekeeping. As a young man, he attended gymnasium in Opava called Troppau in German. He had to take four months off during his gymnasium studies due to illness. From to , he studied practical and theoretical philosophy and physics at the Philosophical Institute of the University of Olomouc , taking another year off because of illness. He also struggled financially to pay for his studies, and Theresia gave him her dowry.
