Why Drosophila is used in research?

Why Drosophila is used in research?

75 per cent of the genes that cause disease in humans are also found in the fruit fly. Drosophila have a short, simple reproduction cycle. Fruit fly are small (3 mm long) but not so small that they can’t be seen without a microscope. This allows scientists to keep millions of them in the laboratory at a time.

What are the conclusions from Drosophila experiment?

He concluded that closer the genes, greater the linkage and vice-versa. Note: He also discovered the white eye mutation in Drosophila. He chooses Droshophila to study the sex-linked genes. The mutation is inherited differently by male and female flies he said.

Who performed experiment on Drosophila?

One day in 1910, American geneticist Thomas Hunt Morgan peered through a hand lens at a male fruit fly, and he noticed it didn’t look right. Instead of having the normally brilliant red eyes of wild-type Drosophila melanogaster, this fly had white eyes.

What did experiments on fruit flies reveal?

In an experiment in fruit flies, or Drosophila melanogaster, researchers at the University of Pennsylvania have found that adding different species of microbes to the flies’ food caused populations to diverge genetically, racking up significant genomic changes in just five generations.

What are some advantages of using Drosophila to study genetics?

Advantages of using Drosophila are as follows: Small and easy to maintain. Can be raised and tested within small laboratory which does not have access time, space or funding. Contains fewer genes than humans, indicating less overall genetic redundancy.

How did Morgan explain his finding?

How did Morgan explain his finding? Linked genes were inherited together because they were close to each other on the same chromosome. The farther apart two genes were on a chromosome, the more likely it would be that crossing-over would occur between them.

Why TH Morgan used Drosophila melanogaster in his genetic experiments?

T. H. Morgan selected Drosophila melanogaster to study sex-linked genes in his lab experiment due to the following reasons: (ii) Sex-linked traits such as red eye colour and white eye colour are found only in Drosophila ​melanogaster, where white eye colour in males is a sex-linked recessive trait.

What was Morgan’s experiment?

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. He predicted and observed that half of the flies would be red-eyed females and the other half would be white-eyed males.

Why did Morgan used Drosophila for his experiment?

What is the purpose of the Drosophila lab?

Experimental methods to study Drosophila in labs. The study of Drosophila in labs serves many purposes which include the understanding of neurons, developmental processes, mutational studies, gene regulation, and signaling. A number of methods are used to study the different processes in different experiments.
