What field of science did Thomas Morgan establish?
Genetics
Physics
Psychology
Chemistry
What is the main idea in Thomas Morgan's Chromosomal Theory of Inheritance?
Genes are located on chromosomes like beads on string, and that genes can be linked to chromosomes.
Chromosomes have nothing to do with inheritance and heredity.
Genes are separate from chromosomes, and they do not interact with one another.
Genes are located on chromosomes, but cannot link to the chromosome.
What species of flies did Thomas Morgan experiment on?
Drosophila Flies
Bluebottle flies
Cluster flies
Horse flies
Why did Thomas Morgan use flies as subjects in his experiments?
They produced large amounts of offspring for Morgan to examine.
He could easily keep them contained.
He had been fascinated by flies since he was a child.
He used flies because he couldn't afford larger test subjects.
Why do we learn about genetics?
To understand the human body, and to create new medical treatments to fight illnesses and mutations in the body.
To learn about the environment.
To get good grades in school.
To become better scientists.
How many X chromosomes do male Drosophila have? How many X chromosomes do Female Drosophila have?
Male drosophila have one X chromosome while female drosophila have two X chromosomes.
Male drosophila have two X chromosomes while female drosophila have one X chromosome.
Male drosophila have no X chromosomes while female drosophila have one X chromosome.
Both male and female drosophila have two X chromosomes.
What might have happened if Thomas Morgan never proved his Chromosomal Theory of Inheritance, or examined flies in his "fly room" experiments? Choose all that apply.
Modern medical treatments for diseases and cancers would have never been created.
Genetics would have never been created into a experimental field.
Nothing would change. We would still have extensive knowledge about modern genetics.
