WHO concluded that the gene for eye color is located on the sex chromosome?
It was Thomas Hunt Morgan who concluded that the gene for eye color is located on the sex chromosome through his work with fruit flies in the early 20th century.
X-linkage was discovered for the first time in?
Genetic linkage was first discovered by the British geneticists William Bateson and Reginald Punnett shortly after Mendel's laws were rediscovered. The understanding of genetic linkage was expanded by the work of Thomas Hunt Morgan. Morgan's observation that the amount of crossing over between linked genes differs led to the idea that crossover frequency might indicate the distance separating genes on the chromosome. Alfred Sturtevant, a student of Morgan's, first developed genetic maps, also known as linkage maps.
What are two conclusions that Thomas Hunter Morgan made about genes and chromosomes?
Thomas Hunter Morgan concluded that genes are located on chromosomes and that they are the primary units responsible for inheritance. He also suggested that the arrangement of genes on chromosomes plays a role in determining an organism's traits and characteristics.
Why was Morgan initially skeptical of Mendel's theories of genetics?
Mutation does not equal speciation( new unchanging species)Morgan realized that one of its genes had been altered and it had produced a new kind of eye. Morgan bred the white-eyed fly with a red-eyed fly and got a generation of red-eyed hybrids. And when he bred the hybrids together, some of the grandchildren were white-eyed. Their ratio was three red to one white. Here was a mutation, but one that didn't fit DeVries's(Mendel's) definition. DeVriesthought that mutations created new species, but the fly that had acquired the white-eyed mutation remained a memberof the same species. It could still mate with other fruit flies, and its gene could be passed down to later generations in proper Mendelian fashion.
Who are four scientist that worked to better understand DNA?
James Watson, Gregor Mendel, Barbra McClintock and Thomas Hunt Morgan
Who develop the gene theory?
Ultimately, Gregor Mendel's statistical approaches to genes, which he called factors, led DeVires, Morgan and other at the turn of the 20th century to develop a theory that explained the workings of genes.
Did Gregor Darwin use fruit flies?
No, Gregor Darwin did not use fruit flies for his experiments. He is best known for his work on evolutionary theory, specifically natural selection and the concept of survival of the fittest. Fruit flies are commonly used in genetics research by scientists such as Thomas Hunt Morgan.
What is the difference between Morgan Stanley and JP Morgan?
The difference between Morgan Stanley and JP Morgan is that they are both different companies. In 1933 the government decided that retail and investments had to be separate so one of the Morgan family founded Morgan Stanley.
Who are the 2 famous scientists who made important contributions in the study of genetics?
Gregor Mendel and Thomas Hunt Morgan are two famous scientists who made important contributions to the study of genetics. Mendel is known for his work on inheritance in pea plants, establishing the laws of heredity, while Morgan discovered the role of chromosomes in inheritance, specifically through his research on fruit flies.
Whose early work is the basis for much our current understanding of genetics?
Mendel discovered the concept of inheritable traits. Johannsen coined the term gene. TH Morgan identified the gene as a distinct locus. Crick, Watson and Franklin elucidated the 3D structure of DNA.

What is the difference between an 1894 silver dollar and an 1894 Morgan silver dollar?
There's no difference. All silver dollars minted in 1894 used the Morgan design, named for the famous designer George T. Morgan.
What is the difference between a silver dollar and a Morgan dollar?
A Morgan dollar IS a silver dollar. The term Morgan refers to the designer George T. Morgan who created the images used from 1878 to 1904 and in 1921.
What is the difference between an 1889 Morgan or liberty silver dollar?
There is no difference. They are the same coin but many people refer to them as "Liberty Dollars".
What conclusions did Morgan arrive at with his experiments on fruit flies and why did they extend Mendel's conclusions?
Morgan concluded that genes are located on chromosomes and that some genes are linked to specific traits. He extended Mendel's conclusions by demonstrating that genes are physically located on chromosomes and can be inherited as a unit, leading to the concept of gene linkage and genetic recombination.
When did Thomas Hunt Morgan die?
Thomas Hunt Morgan died on December 4, 1945 at the age of 79.
