Was konnte Thomas Hunt 1911 nachweisen?
1910 gelang ihm bei Versuchen mit Drosophila melanogaster, so ihr wissenschaftlicher Name, erstmalig die exakte Lokalisation eines Gens auf den Chromosomen der Tierchen. 1911 erstellte MORGAN die erste Chromosomenkarte der Drosophila, Dutzende von Kartierungen folgten.
Was besagt die Chromosomentheorie?
Die Chromosomentheorie der Vererbung besagt, dass sich die Erbinformationen auf den Chromosomen im Zellkern befinden. Die im Jahr 1903 aufgestellte Theorie wurde durch die Erkenntnisse der modernen Molekularbiologie umfangreich bestätigt.

Who is Thomas Hunt Morgan and what did he do?
Thomas Hunt Morgan. Written By: Thomas Hunt Morgan, (born Sept. 25, 1866, Lexington, Ky., U.S.—died Dec. 4, 1945, Pasadena, Calif.), American zoologist and geneticist, famous for his experimental research with the fruit fly (Drosophila) by which he established the chromosome theory of heredity.
What did Thomas Hunt Morgan discover about the genetic basis of inheritance?
At first, the American geneticist Thomas Hunt Morgan dismissed that concept. Later, however, when he found that it agreed with his own laboratory findings, Morgan and his collaborators assigned the hereditary units (genes) specific positions, or loci, within the chromosomes. With the genes established as the carriers of hereditary traits,…
Where did William Morgan go on his research trip?
Based on the publication of this work, Morgan was awarded his Ph.D. from Johns Hopkins in 1890, and was also awarded the Bruce Fellowship in Research. He used the fellowship to travel to Jamaica, the Bahamas and to Europe to conduct further research.
What was the conclusion of the Morgan’s Research?
He concluded that with respect to embryology, they were more closely related to spiders than crustaceans. Based on the publication of this work, Morgan was awarded his Ph.D. from Johns Hopkins in 1890, and was also awarded the Bruce Fellowship in Research.
