How were fruit flies used in genetic research?

Fruit flies have a very simple genetic structure, which makes them ideal for genetic research. It is useful to study mutant fruit flies, as their quick reproduction rate allows scientists to observe the advantages and disadvantages of certain mutations.

Who used fruit flies to study genetics?

Morgan’s work on the role of chromosomes in heredity was recognized in 1933 with the Nobel Prize in physiology or medicine. He continued to work until his death on December 4, 1945, at age 79. Colleagues remember him as a generous man with an infectious enthusiasm for his work.

What are fruit flies used for in research?

The fruit fly, Drosophila melanogaster, is used as a model organism to study disciplines ranging from fundamental genetics to the development of tissues and organs.

Are fruit flies harmful?

There are hidden dangers that most people are unaware of, that make these tiny little fruit flies a human health hazard. Dangerous bacteria and other germs can stick to their hairy bodies, that can get on our food or hands and spread illnesses that cause health problems, especially diarrhea.

Why did NASA send fruit flies to space?

1940s. The first animals sent into space were fruit flies aboard a U.S.-launched V-2 rocket on 20 February 1947 from White Sands Missile Range, New Mexico. The purpose of the experiment was to explore the effects of radiation exposure at high altitudes. … The fruit flies were recovered alive.

What do humans and fruit flies have in common?

Genetically speaking, people and fruit flies are surprisingly alike, explains biologist Sharmila Bhattacharya of NASA’s Ames Research Center. “About 61% of known human disease genes have a recognizable match in the genetic code of fruit flies, and 50% of fly protein sequences have mammalian analogues.”

What is the difference between male and female fruit flies?

The most simple characteristic to use to differentiate the two is to look at the genitalia of the flies. Males have dark, rounded genitalia at the tip of their abdomen, whereas females have light, pointed genitalia. … Male Drosophila are generally smaller than their female counterparts, and have a darker abdomen.
