Thomas Hunt Morgan's experiments.

Answer 2

3. Morgan carried out experiments on Drosophila melanogaster to study linkage.

Linkage:

• The tendency for DNA sequences that are near to one another on a chromosome to be passed down together during the meiosis stage of sexual reproduction is known as genetic linkage.
• When two or more genes are linked together, they are always passed down in the same combination for more than two generations. In contrast, when genes are recombined between distinct organisms, the result is offspring with the combined features.
• The windshield wiper, bicycle suspension, walking machine leg mechanism, and hydraulic actuators for large machinery are all interesting examples of links.
• These are instances of planar links, which are made up of parts that move in parallel planes.

Thomas Hunt Morgan:

• American geneticist Thomas Hunt Morgan once observed a male fruit fly through a hand lens and thought it didn't look quite right.
• This fly has white eyes instead of the wild-type Drosophila melanogaster's characteristically vivid red eyes.
