Who is Thomas Hunt Morgan and what did he do?

Who is Thomas Hunt Morgan and what did he do?

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 chromosomes in fruit flies?

Thomas Hunt Morgan, who studied fruit flies, provided the first strong confirmation of the chromosome theory. ... He observed that the mutation was inherited differently by male and female flies. Based on the inheritance pattern, Morgan concluded that the eye color gene must be located on the X chromosome.

How did Thomas Hunt Morgan make his discovery?

Learn about Thomas Hunt Morgan, the first person to definitively link trait inheritance to a specific chromosome and his white-eyed flies. One day in 1910, American geneticist Thomas Hunt Morgan peered through a hand lens at a male fruit fly, and he noticed it didn't look right.

Why did Thomas Hunt Morgan Choose fruit flies?

Morgan decided to use fruit flies to study how physical traits (for example, eye color) were transmitted from parents to offspring, and he was able to elegantly show that genes are stored in chromosomes and form the basis of heredity.

What did Thomas Morgan study?

Following the rediscovery of Mendelian inheritance in 1900, Morgan began to study the genetic characteristics of the fruit fly Drosophila melanogaster. In his famous Fly Room at Columbia University's Schermerhorn Hall, Morgan demonstrated that genes are carried on chromosomes and are the mechanical basis of heredity.

Where did Thomas Hunt Morgan study?

Johns Hopkins University University of Kentucky Thomas Hunt Morgan/Istruzione He was educated at the University of Kentucky, where he took his B.S. degree in 1886, subsequently doing postgraduate work at Johns Hopkins University, where he studied morphology with W. K. Brooks, and physiology with H. Newell Martin.

Why TH Morgan used Drosophila melanogaster in his genetic experiment?

T. H. Morgan selected Drosophila melanogaster to study sex-linked genes in his lab experiment due to the following reasons: ... (ii) Sex-linked traits such as red eye colour and white eye colour are found only in Drosophila ​melanogaster, where white eye colour in males is a sex-linked recessive trait.

What did Thomas Hunt Morgan discovered that seemed to violate Mendel's principles?

What did Thomas Hunt Morgan discover that seemed to violate Mendel's principles? Thomas Morgan discovered that some genes appeared to be linked; This seemed to violate the principle of independent assortment.

What did Morgan conclude from his research?

4. What did Morgan conclude from his research on fruit flies? Linked genes are on the same chromosome; chromosomes, not genes, assort independently during meiosis; homologous genes can be exchanged through cross-overs during meiosis.

What organism did Morgan and his colleagues use to develop the chromosomal theory of inheritance What traits did they track?

Thomas Hunt Morgan () and his colleagues spent several years carrying out crosses with the fruit fly, Drosophila melanogaster. They performed meticulous microscopic observations of fly chromosomes and correlated these observations with resulting fly characteristics.
