What You'll Learn
Gregor Mendel was Austrian
Gregor Mendel was an Austrian scientist, teacher, monk, biologist, meteorologist, mathematician, Augustinian friar, and abbot of St. Thomas' Abbey in Brno (Brünn), Margraviate of Moravia. He was born in Heinzendorf, Silesia, Austrian Empire (now Hynčice, Czech Republic) on July 20, 1822, and died in Brünn, Austria-Hungary (now Brno, Czech Republic) on January 6, 1884.
Mendel is known as the "father of modern genetics" for his discovery of the basic principles of heredity through experiments in his monastery's garden. He raised and monitored more than 20,000 pea plants inside the walls of his monastery, studying the inheritance of traits in these plants. Mendel's observations became the foundation of modern genetics and the study of heredity, and he is widely considered a pioneer in the field of genetics.
Mendel chose to study 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—such as tall with short, smooth with wrinkled, or green seeds with yellow seeds—and analyzed his results. Mendel discovered that many characteristics of peas had an either-or configuration; for example, pea plants were either tall (up to six feet) or dwarf (no more than 20 inches), seeds were either green or yellow, and either round or “wrinkled,” with no blending when two variations were crossed.
Through his careful breeding of pea plants, 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, now referred to as Mendelian inheritance. Mendel's work was not fully recognized until the turn of the 20th century, when several noted geneticists, botanists, and biologists conducting research on heredity rediscovered his work and began to understand its significance.

He was a monk
Gregor Mendel was an Austrian monk who discovered the basic principles of heredity through experiments in his garden. Mendel's observations became the foundation of modern genetics and the study of heredity, and he is widely considered a pioneer in the field of genetics.
Mendel was born in 1822 in Heinzendorf, Austria. He spent his early youth in a rural setting until the age of 11, when a local schoolmaster recommended that he be sent to secondary school in Troppau to continue his education. Mendel excelled in his studies and graduated from school with honours in 1840. Following his graduation, he enrolled in a two-year program at the Philosophical Institute of the University of Olmütz. There, he distinguished himself academically, particularly in physics and mathematics. Despite suffering from bouts of depression that caused him to temporarily abandon his studies, Mendel graduated from the program in 1843.
That same year, against his father's wishes, Mendel joined the Augustinian order at the St. Thomas Monastery in Brno and was given the name Gregor. At that time, the monastery was a cultural centre for the region, and Mendel was exposed to the research and teaching of its members. He also gained access to the monastery's extensive library and experimental facilities.
In 1849, exhausted from his work in the community in Brno, Mendel was sent to fill a temporary teaching position in Znaim. However, he failed a teaching certification exam the following year and was sent to the University of Vienna in 1851 to continue his studies in the sciences. While there, Mendel studied mathematics and physics under Christian Doppler, after whom the Doppler effect of wave frequency is named. He also studied botany under Franz Unger, a proponent of a pre-Darwinian version of evolutionary theory.
Mendel returned to the monastery in Brno in 1853 and was given a teaching position at a secondary school, where he remained for more than a decade. It was during this time that he began the experiments for which he is best known. 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-fertilised pea plants that had clearly opposite characteristics and, after analysing his results, reached two of his most important conclusions: the Law of Segregation and the Law of Independent Assortment.
Mendel's experiments showed that the inheritance of certain traits in pea plants follows particular patterns. He discovered that there was particulate inheritance of traits according to basic laws of inheritance. Mendel's studies became the foundation of modern genetics and he is widely considered the "father of genetics".

He discovered the basic principles of heredity
Gregor Mendel, the "father of modern genetics", discovered the basic principles of heredity through experiments with pea plants. Mendel was an Austrian monk and scientist who lived in the 1800s. He studied natural sciences and mathematics at the University of Vienna, Austria, but twice failed to obtain a teaching certificate.
Mendel's most famous experiments were conducted between 1856 and 1864, during which time he grew some 10,000 pea plants. Pea plants are hermaphroditic, meaning they have both male and female sex cells and usually self-fertilise. However, Mendel was able to cross-breed the plants by transferring pollen with a paintbrush. He meticulously recorded a range of characteristics for each plant, including its height, pod shape, seed shape and seed colour.
At the time, it was widely believed that heredity worked by blending the characteristics of parents, producing offspring that were diluted versions of their parents. Mendel's experiments showed that this was not the case. When two varieties of purebred plants cross-breed, the offspring resemble one or the other parent, not a blend of the two. He found that some traits are dominant and are always expressed in the first generation of cross-bred plants, while others are recessive and do not appear until the next generation.
Mendel hypothesised that parents contribute some particulate substance to the offspring, which determines its characteristics. We now know that these particles are genes made of DNA. Mendel inferred that these heritable particles are separated into gametes (eggs and sperm) and that offspring inherit one particle from each parent.
Mendel's work laid the foundation for the science of genetics and led to the development of new experimental methods. His findings also contributed to the modern synthesis of evolutionary biology, a reformulation of Darwin's ideas based on the new understanding of genetics.

He is known as the father of genetics
Gregor Mendel is known as the "father of genetics" because his experiments with pea plants laid the foundation of modern genetics and the study of heredity. Mendel's experiments showed that the inheritance of certain traits in pea plants follows particular patterns.
Mendel, an Austrian monk, discovered the basic principles of heredity through experiments in his monastery's garden. He chose to study variation in plants in his monastery's 2 hectares (4.9 acres) experimental garden. Mendel was assisted in his experimental design by Aleksander Zawadzki. He conducted his experiments between 1856 and 1863, cultivating and testing some 28,000 plants, the majority of which were pea plants.
Mendel worked with seven characteristics of pea plants: plant height, pod shape and color, seed shape and color, and flower position and color. Taking seed color as an example, Mendel showed that when a true-breeding yellow pea and a true-breeding green pea were cross-bred, their offspring always produced yellow seeds. However, in the next generation, the green peas reappeared at a ratio of 1 green to 3 yellow. To explain this phenomenon, Mendel coined the terms "recessive" and "dominant" in reference to certain traits. In the preceding example, the green trait, which seems to have vanished in the first filial generation, is recessive, and the yellow is dominant.
Mendel's approach to experimentation came from his training in physics and mathematics, especially combinatorial mathematics. The latter served him ideally to represent his result. If A represents the dominant characteristic and a the recessive, then the 1:2:1 ratio recalls the terms in the expansion of the binomial equation: (A + a)2 = A2 + 2Aa + a2. Mendel realized further that he could test his expectation that the seven traits are transmitted independently of one another. Crosses involving first two and then three of his seven traits yielded categories of offspring in proportions following the terms produced from combining two binomial equations, indicating that their transmission was independent of one another. Mendel’s successors have called this conclusion the law of independent assortment.

His work laid the foundation for genetics
Gregor Mendel is widely known as the "father of modern genetics". Through his experiments on pea plants, Mendel discovered the basic principles of heredity and laid the foundation for the science of genetics.
Mendel was born in 1822 in Heinzendorf, Silesia, Austrian Empire (now Hynčice, Czech Republic). He was raised in a rural setting and attended a local grammar school. After completing his studies, he joined the Augustinian order at the St. Thomas Monastery in Brno, where he was given the name Gregor. Mendel's monastery was a cultural hub in the region, and he was exposed to extensive research and teaching, as well as access to experimental facilities.
Mendel's experiments focused on studying seven characteristics of pea plants: plant height, pod shape and colour, seed shape and colour, and flower position and colour. He chose pea plants due to their numerous distinct varieties and the ease of culture and control of pollination. Mendel's experiments revealed that when a true-breeding yellow pea and a true-breeding green pea were cross-bred, their offspring always produced yellow seeds. However, in the next generation, the green peas reappeared at a ratio of 1 green to 3 yellow. To explain this phenomenon, Mendel coined the terms ""recessive" and "dominant" in reference to certain traits.
Mendel's findings led him to formulate several basic genetic laws, including the law of segregation, the law of dominance, and the law of independent assortment, now collectively known as Mendelian inheritance. Mendel's work demonstrated the actions of invisible "factors", now called genes, in determining the traits of an organism. Mendel's experiments provided an alternative to the dominant theory of the time, blending inheritance, which stated that the hereditary traits of offspring were a diluted blending of their parents' traits.
Mendel's work laid the foundation for the field of genetics, and he is considered a pioneer in this area. His findings were not fully recognised until the turn of the 20th century when several geneticists, botanists, and biologists conducted research on heredity, building upon Mendel's discoveries.
