What is the purpose of the Drosophila lab?
What is the purpose of the Drosophila lab?
The purpose of this experiment was to learn about Drosophila melanogaster and some of its mutations, to study sex linkage, recombination and independent assortment.
Why are Drosophila used in genetic experiments?
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.
How many Drosophila labs are there?
six Drosophila labs
There are currently six Drosophila labs that utilize the Drosophila Facility (Drs. Allan, Auld, Brock, Gordon, Grigliatti, Tanentzapf), as well as three collaborating labs (Drs. Accili, Numata, O’Connor) that take advantage of Drosophila in specific lab projects.
How do I get Virgin Drosophila?
Remove all flies 8-10 hours before collecting (generally this is done first thing in the morning). Visually inspect surface of food to ensure complete removal of flies. After 8-10 hours (usually before you leave work) collect all females that are present. All will be virgins.
Where are Drosophila melanogaster found?
having a worldwide distribution. Found on all continents (except maybe Antarctica) and in all biogeographic provinces; or in all the major oceans (Atlantic, Indian, and Pacific.
How many genes does Drosophila have?
The Drosophila melanogaster complete genome sequence was published in 2000. It contains 180 Mb (one third of which is centric heterochromatin) and approximately 14,000 protein-coding genes.
Why is Drosophila called fruit fly?
Drosophila derived from the Greek word drósos means dew loving. They belong to the Droso–philidae family; and are most frequently known as fruit flies or often called vinegar, wine or pomace flies. Their main distinguishing character is to stay on fruits, which are ripped or rotten.
How do Drosophila reproduce?
Reproduction in Drosophila is rapid. As in all insect species Drosophila melanogaster lays eggs. The eggs are placed on fruit, and hatch into fly larvae (maggots), which instantly start consuming the fruit on which they were laid (Patterson and Stone 1952).
How is culture media prepared for Drosophila?
Drosophila media preparation
- Weigh corn flour, D-Glucose, Sugar, Agar and yeast powder separately and keep them aside.
- Take the required quantity of water based on the need (for example, for 6ltrs of fly media, take 6ltrs of water) in a pressure cooker.
- Warm the water (approximate temperature 35⁰C) and add corn flour.
What are the scientific name and common name of Drosophila melanogaster?
Drosophila melanogasterCommon fruit fly / Scientific name
Can Drosophila melanogaster be used to observe phenotypes of offspring?
This lab report aims at crossing various traits of the Drosophila melanogaster to observe phenotypes of offspring. The researcher intends to compare phenotypic ratios of perceived offspring to anticipated ratios found in Mendel’s studies.
What are the 5 types of mutations in Drosophila?
Five mutations were involved in the Drosophila lab report, which included the yellow body, the white eyes, the sepia eyes, the dumpy wings, as well as the black body. The mutation refers to the alternative phenotype to wild types.
How long does it take for Drosophila melanogaster to produce larvae?
For the yellow body and the white cross, the two white virgins were placed in with a single yellow male. The flies produced the larvae after 14 days, and the parents were moved to the new vial. In the test, the F1 generation of the Drosophila melanogaster had been vestigial or ebony.
What is the expected phenotypic ratio for a cross with red-eyed flies?
We hypothesized that the expected phenotypic ratio for a cross with red-eyed flies would be 3:1 because according to the Mendelian Law of Segregation, the two alleles are separated from each other during gamete formation.
