Anne Mae Lutz
Anne Mae Lutz (March 18, 1871 – January 15, 1938) was an American plant geneticist. She studied mutations in ''Oenothera lamarckiana'' and demonstrated that the mutation ''gigas'' had an extra set of chromosomes leading to studies on the artificial induction of polyploidy. Life and work Lutz was one of eight children of Samuel B. and Eleanor E. (Gougar) Lutz. She studied in a one-room school in Union Township before joining Purdue University where she received a BS in 1890 after just three years of study. She received an MS in 1891 in biology and received another BS from the University of Michigan in 1893 where she was influenced by Volney M. Spaulding. She then worked as a cytologist at Columbia University and then went to the University of Chicago for a year working with William Lawrence Tower. Tower was a student of Charles Davenport who hired her in 1903 to joined the Carnegie Institute of Experimental Evolution, Cold Springs Harbor, where she worked with Hugo de Vries, Ge ...

Oenothera Lamarckiana
''Oenothera glazioviana'' is a species of flowering plant in the evening primrose family known by the common names large-flowered evening-primrose and redsepal evening primrose. ''Oenothera lamarckiana'' was formerly believed to be a different species, but is now regarded as a synonym of ''Oe. glazioviana''. The plant can be found in scattered locations worldwide, mostly as an introduced species. It originated in Brazil. It has long been cultivated as an ornamental plant. In some locations it has become an invasive species. Description ''Oenothera glazioviana'' is generally a biennial herb producing an erect stem approaching in maximum height. It is roughly hairy in texture, the hairs with reddish blistering or glandular bases. The crinkly leaves are up to 15 centimeters long. The inflorescence is a showy spike of many large flowers. When in bud the long red sepals are visible. When in bloom each flower has four bright yellow petals up to 5 centimeters long which fade or ...

Polyploidy
Polyploidy is a condition in which the cells of an organism have more than two paired sets of ( homologous) chromosomes. Most species whose cells have nuclei (eukaryotes) are diploid, meaning they have two complete sets of chromosomes, one from each of two parents; each set contains the same number of chromosomes, and the chromosomes are joined in pairs of homologous chromosomes. However, some organisms are polyploid. Polyploidy is especially common in plants. Most eukaryotes have diploid somatic cells, but produce haploid gametes (eggs and sperm) by meiosis. A monoploid has only one set of chromosomes, and the term is usually only applied to cells or organisms that are normally diploid. Males of bees and other Hymenoptera, for example, are monoploid. Unlike animals, plants and multicellular algae have life cycles with two alternating multicellular generations. The gametophyte generation is haploid, and produces gametes by mitosis; the sporophyte generation is diploid and p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Union Township, Union County, New Jersey
Union Township is a township in Union County, in the U.S. state of New Jersey. In the 18th century, the area that is now Union was then called Connecticut Farms. As of the 2020 United States census, the township's population was 59,728, an increase of 3,086 (+5.4%) from the 2010 census count of 56,642, which in turn reflected an increase of 2,237 (+4.1%) from the 54,405 counted in the 2000 census. History Settled in 1667, Union was the third English speaking settlement in New Jersey after Elizabeth and Newark, with the area that is now Union then called Connecticut Farms. Union Township was the site of the Battle of Connecticut Farms. On June 6, 1780, British troops, led by Hessian General Wilhelm von Knyphausen, boarded boats on Staten Island bound for Elizabeth, New Jersey. At midnight, 5,000 troops started to land. They expected the Continental Army to give little resistance, believing that they were tired of the war and were poorly fed and paid. They also expect ...

William Lawrence Tower
William Lawrence Tower (22 December 1872– July 1967) was an American zoologist, born in Halifax, Massachusetts. He was educated at the Lawrence Scientific School (Harvard), the Harvard Graduate School, and the University of Chicago ( B. S., 1902), where he taught thereafter, becoming associate professor in 1911. Research Tower was notable for his experimental work in heredity, investigating the inheritance of acquired characteristics and the laws of heredity in beetles and publishin''An Investigation of Evolution in Chrysomelid Beetles of the Genus Leptinotarsa''(1906). This study is probably the first (albeit possibly discredited) of mutation in animals. He published also ''The Development of the Colors and Color Patterns of Coleoptera'' (1903) and, with Coulter, Castle, Davenport and East, an essay on ''Heredity and Eugenics'' (1912). Tower was caught up in personal and professional scandals. He resigned from the University of Chicago in 1917 following a very public di ...

Charles Davenport
Charles Benedict Davenport (June 1, 1866 – February 18, 1944) was a biologist and eugenicist influential in the American eugenics movement. Early life and education Davenport was born in Stamford, Connecticut on June 1, 1866, to Amzi Benedict Davenport, an abolitionist of Puritan ancestry, and his wife Jane Joralemon Dimon (of English, Dutch and Italian ancestry). Davenport was exceedingly proud of his ancestry, claiming in 1942 that he had been an American "for over three hundred years" because he was "composed of elements that were brought to this country during the 17th century." His father had eleven children by two wives, and Charles grew up with his family on Garden Place in Brooklyn Heights. His mother's strong beliefs tended to rub off onto Charles and he followed the example of his mother. During the summer months, Charles and his family spent their time on a family farm near Stamford. Due to Davenport's father's strong belief in Protestantism, as a young boy Char ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hugo De Vries
Hugo Marie de Vries (; 16 February 1848 – 21 May 1935) was a Dutch botanist and one of the first geneticists. He is known chiefly for suggesting the concept of genes, rediscovering the laws of heredity in the 1890s while apparently unaware of Gregor Mendel's work, for introducing the term "mutation", and for developing a mutation theory of evolution. Early life De Vries was born in 1848, the eldest son of Gerrit de Vries (1818–1900), a lawyer and deacon in the Mennonite congregation in Haarlem and later Prime Minister of the Netherlands from 1872 until 1874, and Maria Everardina Reuvens (1823–1914), daughter of a professor in archaeology at Leiden University. His father became a member of the Dutch Council of State in 1862 and moved his family over to The Hague. From an early age Hugo showed much interest in botany, winning several prizes for his herbariums while attending gymnasium in Haarlem and The Hague. In 1866 he enrolled at the Leiden University to major in bot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Harrison Shull
George Harrison Shull (April 15, 1874 – September 28, 1954) was an American plant geneticist and the younger brother of botanical illustrator and plant breeder J. Marion Shull. He was born on a farm in Clark County, Ohio, graduated from Antioch College in 1901 and from the University of Chicago ( Ph.D.) in 1904, served as botanical expert to the Bureau of Plant Industry in 1903–04, and thenceforth was a botanical investigator of the Carnegie Institution at the Station for Experimental Evolution, Cold Spring Harbor, N. Y., giving special attention to the results of Luther Burbank's work. Shull played an important role in the development of hybrid maize (in the USA, popularly 'corn') which had great impact upon global agriculture. As a geneticist, Shull worked with maize plants. He was interested in pure breeds not for their economic value but for his experiments in genetics. He produced maize breeds that bred true and then crossed these strains. The hybrid offspring of ...
