What organism did Thomas Hunt Morgan study?
What organism did Thomas Hunt Morgan study?
Drosophila
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 organism did Thomas Hunt Morgan use to confirm the chromosomal theory of inheritance?
It was only after several years of carrying out crosses with the fruit fly, Drosophila melanogaster, that Thomas Hunt Morgan provided experimental evidence to support the Chromosomal Theory of Inheritance.
Why did Morgan use fruit flies as his experimental organism?
Morgan chose the fruit fly, Drosophila melanogaster, for his genetic studies. What fruit flies may lack in charisma (depending on your taste in insects), they make up for in practicality: they’re cheap, easy, and fast to grow.
What was Morgan’s experiment?
Morgan hypothesized that, in his breeding experiment, the first generation of flies contained males only with white eyes because the gene controlling eye color was on the X chromosome. He predicted and observed that half of the flies would be red-eyed females and the other half would be white-eyed males.
What was the observation done by Morgan?
Morgan Detects an Unusual Pattern of Inheritance To test this idea, Morgan then crossed males and females from the F1 generation to probe for a pattern of white eye reoccurrence. Upon doing so, he observed a 3:1 ratio of red eyes to white eyes in the F2 generation.
What did Thomas Hunt Morgan discover?
Thomas Hunt Morgan was awarded the Nobel Prize in Physiology or Medicine in 1933. The work for which the prize was awarded was completed over a 17-year period at Columbia University, commencing in 1910 with his discovery of the white-eyed mutation in the fruit fly, Drosophila.
What experiment did Thomas Hunt Morgan do?
In 1910, Thomas Hunt Morgan performed an experiment at Columbia University, in New York City, New York, that helped identify the role chromosomes play in heredity. That year, Morgan was breeding Drosophila, or fruit flies.
What did Morgan discover during his studies of fruit flies?
In brief, Morgan had discovered that eye color in Drosophila expressed a sex-linked trait. All first-generation offspring of a mutant white-eyed male and a normal red-eyed female would have red eyes because every chromosome pair would contain at least one copy of the X chromosome with the dominant trait.
What scientific contribution was made by TH Morgan and his students?
Concept 10 Chromosomes carry genes. Thomas Hunt Morgan was one of the first true geneticists. He and his “Fly group” made tremendous contributions to our understanding of the role of chromosomes and genes in inheritance.
What was Thomas Hunt Morgan’s main contribution to science?
What was Thomas Hunt Morgan’s main contribution to science? He discovered that certain traits were linked to the X chromosome. Which allele combination represents a female who is a carrier for an X-linked recessive disorder?
