Suresh Jayakar
Suresh Dinakar Jayakar (21 September 1937, Bombay – 21 January 1988) was an Indian biologist who pioneered in the use of quantitative approaches in genetics and biology. He studied mathematical statistics, physics and mathematics at the University of Lucknow and joined the Indian Statistical Institute in 1959 where he met J. B. S. Haldane who had just moved to India. At that institute, Jayakar received early instruction in genetics in a course taught by Krishna Dronamraju and additional training with Helen Spurway. He moved to Orissa when Haldane moved. He became the director of the Genetics and Biometry Laboratory after Haldane's death. He made many studies on yellow-wattled lapwing The yellow-wattled lapwing (''Vanellus malabaricus'') is a lapwing that is endemic to the Indian Subcontinent. It is found mainly on the dry plains of peninsular India and has a sharp call and is capable of fast flight. Although they do not migr ...s along with Helen Spurway. He collaborated ...

Indian Statistical Institute
Indian Statistical Institute (ISI) is a higher education and research institute which is recognized as an Institute of National Importance by the 1959 act of the Indian parliament. It grew out of the Statistical Laboratory set up by Prasanta Chandra Mahalanobis in Presidency College, Kolkata. Established in 1931, this unique institution of India is one of the oldest institutions focused on statistics, and its early reputation led it to being adopted as a model for the first US institute of statistics set up at the Research Triangle, North Carolina by Gertrude Mary Cox. Mahalanobis, the founder of ISI, was deeply influenced by the wisdom and guidance of Rabindranath Tagore and Brajendranath Seal. Under his leadership, the institute initiated and promoted the interaction of statistics with natural and social sciences to advance the role of statistics as a key technology by explicating the twin aspectsits general applicability and its dependence on other disciplines for its own d ...

Krishna Dronamraju
Dronamraju Krishna Rao (14 January 1937 – 3 December 2020) was an Indian-born geneticist and president of the Foundation for Genetic Research in Houston, Texas. He was born in Pithapuram, in the state of Andhra Pradesh, India. One focus of his work has been the research of his mentor J. B. S. Haldane. As an author, his name is usually rendered Krishna R. Dronamraju. He died in Houston at age 83. Biography Education Dronamraju went to M. R. College in Vizianagaram, Andhra University to study botany and earned a bachelor's degree in 1955. He received a master's degree from Agra University in 1957; he studied plant breeding and genetics. When J.B.S. Haldane moved to India in 1957, Dronamraju wrote to Haldane for an opportunity to pursue a research career under his direction at the Indian Statistical Institute in Calcutta. Early in his research career, he discovered the first case of a gene on the human Y chromosome and published a paper in 1960. It was also part of his PhD the ...

Helen Spurway
Helen Spurway (12 June 1915 – 15 February 1978) was a British biologist and the second wife of J. B. S. Haldane. She emigrated to India in 1957 along with him and conducted research in field biology with Krishna Dronamraju, Suresh Jayakar, and others. Sometimes known as Helen Spurway-Haldane. Life and career Spurway was born in 1915 in the London borough of Wandsworth, the daughter of Frank Spurway and Kate Lea, who were employees of the Post Office, as a telegraphist and a telegraphist and postal clerk. She obtained her Ph.D. in genetics in 1938 at University College London under the supervision of Haldane, whom she met as an undergraduate and married in 1945. Her early research was in the genetics of ''Drosophila subobscura'', but later switched to the reproductive biology of the guppy, '' Lebistes reticulatus''. Her claim, in 1955, that parthenogenesis, which occurs in the guppy in nature, may also occur (though very rarely) in the human species, leading to so-called "virgin ...

Yellow-wattled Lapwing
The yellow-wattled lapwing (''Vanellus malabaricus'') is a lapwing that is endemic to the Indian Subcontinent. It is found mainly on the dry plains of peninsular India and has a sharp call and is capable of fast flight. Although they do not migrate, they are known to make seasonal movements in response to rains. They are dull grey brown with a black cap, yellow legs and a triangular wattle at the base of the beak. Like other lapwings and plovers, they are ground birds and their nest is a mere collection of tiny pebbles within which their well camouflaged eggs are laid. The chicks are nidifugous, leaving the nest shortly after hatching and following their parents to forage for food. Taxonomy The yellow-wattled lapwing was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in his ''Histoire Naturelle des Oiseaux'' in 1781. The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the ''Planches Enluminées D'Histoire Na ...

Sceliphron
''Sceliphron'', also known as black mud daubers or black mud-dauber wasps, is a genus of Hymenoptera of the Sphecidae family of wasps. They are solitary mud daubers and build nests made of mud. Nests are frequently constructed in shaded niches, often just inside of windows or vent openings, and it may take a female only a day to construct a cell requiring dozens of trips carrying mud. Females will add new cells one by one to the nest after each cell is provisioned. They provision these nests with spiders, such as crab spiders, orb-weaver spiders and jumping spiders in particular, as food for the developing larvae. Each mud cell contains one egg and is provided with several prey items. Females of some species lay a modest average of 15 eggs over their whole lifespan. Various parasites attack these nests, including several species of cuckoo wasps, primarily by sneaking into the nest while the resident mud dauber is out foraging. As is the case with many insect genera, there are ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Luigi Luca Cavalli-Sforza
Luigi Luca Cavalli-Sforza (; 25 January 1922 – 31 August 2018) was an Italian geneticist. He was a population geneticist who taught at the University of Parma, the University of Pavia and then at Stanford University. Works Schooling and positions Cavalli-Sforza entered Ghislieri College in Pavia in 1939 and he received his M.D. from the University of Pavia in 1944.

University Of Pavia
The University of Pavia ( it, Università degli Studi di Pavia, UNIPV or ''Università di Pavia''; la, Alma Ticinensis Universitas) is a university located in Pavia, Lombardy, Italy. There was evidence of teaching as early as 1361, making it one of the oldest universities in the world. It was the sole university in Milan and the greater Lombardy region until the end of the 19th century. In 2022 the University was recognized by the Times Higher Education among the top 10 in Italy and among the 300 best in the world. Currently, it has 18 departments and 9 faculties. It does not have a main campus; its buildings and facilities are scattered around the city, which is in turn called "a city campus." The university caters to more than 20,000 students who come from Italy and all over the world. The university offers more than 80 undergraduate programs; over 40 master programs, and roughly 20 doctoral programs (including 8 in English). About 1,500 students who enter the university every ...

University Of Lucknow Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university i ...
