Morgan, Thomas Hunt US geneticist who helped establish that the genes are located on the chromosomes, discovered sex chromosomes, and invented the techniques of genetic mapping. He was the first to work on the fruit fly Drosophila, which has since become a major subject of genetic studies. Nobel Prize for Physiology or Medicine 1933. Morgan was born in Lexington, Kentucky, and studied at Johns Hopkins University. He was professor of experimental zoology at Columbia University 1904-28, when he was appointed director of the Laboratory of Biological Sciences at the California Institute of Technology. Following the rediscovery of Austrian scientist Gregor Mendel's work), Morgan's interest turned from embryology to the mechanisms involved in heredity, and in 1908 he began his research on the genetics of Drosophila. From his findings he postulated that certain characteristics are sex-linked, that the X-chromosome carries several discrete hereditary units (genes), and that the genes are linearly arranged on chromosomes. He also demonstrated that sex-linked characters are not invariably inherited together, from which he developed the concept of crossing-over and the associated idea that the extent of crossing-over is a measure of the spatial separation of genes on chromosomes. Morgan published a summary of his work in The Mechanism of Mendelian Heredity 1915.

["Thomas Hunt Morgan and the chromosome theory: from critic to defender"] Lilian Al-Chueyr Pereira Martins Artigo publicado em: Resumo ["Thomas Hunt Morgan and the chromosome theory: from critic to defender"] Paper published in: Abstract : Nowadays Thomas Hunt Morgan is usually associated with Drosophila genetics and chromosome theory. However, until 1910, he was a strong opponent of this theory. The aim of this paper is to discuss Morgan's change of opinion towards this issue, taking into account the context of his own time. Although scholars have offered several acceptable explanations for his rejection to chromosome theory, there is still no satisfactory explanation for his "conversion". The present paper defends that Morgan's change of attitude towards chromosome theory was due to a professional strategy.

Recommended Link: http://www.geocities.com/plin9k THOMAS HUNT MORGAN "LA HERENCIA CROMOSÓMICA" ¿Cuál es la razón que todos los biólogos del mundo están de acuerdo en afirmar que el descubrimiento de Mendel tiene capital importancia? Son múltiples. Pero lo esencial puede resumirse con breves palabras. La biología ha sido, y en gran parte sigue siendo aún, ciencia descriptiva y especulativa. Mendel demostró con pruebas experimentales que la herencia puede explicarse por medio de un mecanismo muy sencillo. Su descubrimiento ha sido en extremo fecundado. La ciencia comienza con frecuencia con ideas muy místicas, acerca de sus problemas. Obtiene su fin cuando sustituye sus barruntos primitivos con hipótesis verificables y resultados previsibles. Esto es lo que hizo la ley de Mendel para la herencia... Permitan extraer su atención sobre unos cuantos de los más interesantes de estos tipos y el modo como en ellos se efectúa la herencia, a fin de exponer cómo también en los tipos salvajes se presentan las mismas clases de herencias que en la clase doméstica. El resultado probará, sin dejar ni la menor duda, que los caracteres de los tipos salvajes se heredan en la mismísima forma que los caracteres de los tipos mudables, verdad que sólo es apreciada por los investigadores de la genética, a pesar del grandísimo alcance que tiene para la teoría de la evolución. Surgió una variedad en que el color del rojo de la hembra difería del color del ojo del macho. La hembra tiene el ojo del color cosina oscura y el macho de cosina amarillenta. Desde el principio esta diferencia fue tan notoria como lo es hoy. Los experimentos de fecundación nos demuestran que el color de cosina del ojo se diferencian en su solo factor variable del color rojo del ojo de la mosca salvaje. Así, pues, con sólo dar un paso apareció aquí un tipo sexualmente dimórfico.

Negli anni 1888-1889, lavorò come ricercatore presso la United States Fish Commission a Woods Hole, in un laboratorio con il quale sarebbe sempre rimasto in contatto. Dopo la Laurea, ottenne anche un lavoro presso la John Hopkins University dove studiò la morfologia e la fisiologia e dove, nel 1890, ottenne il titolo di dottore di ricerca presentando una tesi sulle relazioni evolutive dei picnogonidi, sotto la guida di W.K.Brooks.
