Mendel Completes Publication of His Research into Genetics
Gregor Johann Mendel, often regarded as the father of modern genetics, completed his groundbreaking research on heredity and gene transmission in plants on March 8, 1865. Born in 1822 in what is now the Czech Republic, Mendel initially pursued studies in natural sciences before joining an Augustinian monastery. His experiments primarily involved cross-pollinating pea plants and meticulously tracking the inheritance of traits, leading to the formulation of foundational laws of heredity. Mendel's research revealed that traits are determined by pairs of genes, with characteristics being influenced by dominant and recessive genes. His findings, published in 1866, went largely unrecognized until the early 20th century when other scientists independently confirmed his conclusions. Despite the initial oversight of his work, Mendel's discoveries revolutionized the understanding of genetics and had significant implications for agriculture and evolutionary biology. After publishing his research, he became abbot of his monastery, which limited his scientific pursuits until his passing in 1884. Mendel's legacy endures, as his work laid the essential groundwork for the field of genetics.

Gregor Johann Mendel, the father of modern genetics, finished reporting his extensive, painstaking research into heredity and gene transmission in plants on March 8, 1865. His work would mark the beginning of a new field of scientific study.
Mendel was born on July 22, 1822, in the Austrian town of Heinzendorf, now the town of Hyncice in the modern-day Czech Republic. As a young man he studied the natural sciences for several years before entering an Augustinian monastery at the Austrian city of Brünn, now Brno in the Czech Republic. Mendel was ordained a priest in 1847, and he also served as a substitute teacher in a local technical school. From 1851 to 1853 the monastery financed his higher education at the University of Vienna, where he continued his studies in the natural sciences, including botany and zoology.
Mendel returned to Brünn in 1854 and resumed his teaching. He also began growing several varieties of peas in a small garden allotted for his use by the monastery, hand-pollinating different plants, harvesting their seeds, and carefully recording and analyzing the transmission of various traits from one generation of plants to the next. In the process he discovered significant patterns. In 1865 Mendel began reporting the results of his research to the Natural Science Society in Brünn. He completed the work on March 8, 1865.
Although his research and conclusions went largely unnoticed at the time, Mendel had in fact discovered the basic laws of heredity. He had deduced that many obvious physical traits, such as the height and flower-color of his pea plants, were governed by pairs of genes, one inherited from each parent. The genes themselves might be either dominant or recessive (Mendel's terms), a recessive gene becoming apparent only in the absence of a dominant one. Whether a particular plant would grow tall or short therefore depended on whether the pair of genes governing its height consisted of two dominants, two recessives, or a combination of both—and there were mathematical ways of expressing this, and ways of breeding plants that would always grow short or tall.
Mendel grew nearly 30,000 pea plants between 1856 and 1863, carefully charting the results of cross-fertilization for various characteristics. (Luckily for him, the traits he was following in pea plants were governed by fairly simple gene pairs: Mendel had no way of knowing that it often takes a complex arrangement of multiple gene pairs to pass on a seemingly simple characteristic in living organisms). His work was published in 1866, but not until the early 20th century, when his conclusions were arrived at independently by other researchers, was he recognized as a pioneering genius. Mendel himself curtailed his research shortly after the publication of his work. He became abbot of the monastery in 1868, and the duties of that position took up most of his time. He died in Brünn on January 6, 1884. His work laid the foundations for the science of genetics and helped clarify the process of evolution. It was also enormously important to agriculture, for it gave plant and animal breeders insights into the workings of heredity.
