Explanation: Fruit flies are organisms with a shorter lifespan. Their average lifecycle takes about a week to develop from lava to an adult. This characteristic of fruit flies are reason they are used for the genetic investigation.
Why are fruit flies commonly used in genetic investigations?
Fruit flies are commonly used in genetic investigations that focus on traits passed from parents to offspring over several generations.
Why did Thomas Morgan use fruit flies?
Thomas Hunt Morgan, an embryologist who had turned to research in heredity, in 1907 began to extensively breed the common fruit fly, Drosophila melanogaster. He hoped to discover large-scale mutations that would represent the emergence of new species. … He isolated this specimen and mated it to an ordinary red-eyed fly.
Why is the fruit fly an invaluable tool for disease research?
The fruit fly is a stand-in for humans, and allows investigation of the molecular mechanisms of 26 human diseases, including ALS. Researchers could use Drosophila melanogaster, because it is a well-established model organism to understand the molecular mechanisms of many human diseases.
What can we learn from fruit flies?
Fruit flies can learn simple tasks, they form memories, and they can also forget. During the learning session, flies are allowed to smell an odor and at the same time they receive a mild shock of electricity. Flies learn that they will feel a bit of pain when they smell the odor.
Why were all the white eyed flies male?
Most of the white-eyed flies were male. … 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. Males displayed the white eye trait because the trait was present on their only X chromosome.
Are fruit flies like humans?
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.”
How much DNA do we share with fruit flies?
Fruit fly: 60 percent identical
These tiny winged creatures share common genes for many biological processes involved with growth and development. In fact, nearly 75 percent of genes that cause disease in humans are also found in fruit flies, making them good models for the study of human disease.
Which is the best example of a hypothesis leading to new experimental methods?
The best example of hypothesis which leads to new experiment methods was done by Morgan where he used fruit flies. Thomas Hunt Morgan continues on genetic research which is of Gregor Mendel.
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.
