What method is suggested for immobilizing the flies?
Cooling Drosophila and sorting them on metal plates chilled on ice baths eliminates the use of toxic or flammable agents, and is a cheap and cost effective method of immobilizing fruit flies (Ratterman, 2003).
Why fruit flies are used for genetic experiments?
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.
What is the phenotype of a fruit fly?
In fruit flies, two possible body color phenotypes are brown and black. Two alleles for body color are brown and black.
Why are fruit flies used for genetic testing?
We are using fruit flies because they are easy to breed and it is easier to tell which genetic mutation that they have. Our group is focusing on the mutation Vestigal, which is a mutation of the wings. The mutation causes the fly’s wings to shrivel and become useless.
Is there a virtual lab for fruit flies?
Drosophilab – this virtual lab requires you to download a program to your computer, students can choose traits to cross and run chi square analysis on outcomes, while this is more basic than the Virtual Courseware lab, it appears to have less bugs
Why do we have to breed fruit flies?
Our class is doing a lab which focuses on the genetic mutations in fruit flies. We are using fruit flies because they are easy to breed and it is easier to tell which genetic mutation that they have. Our group is focusing on the mutation Vestigal, which is a mutation of the wings.
What do the chromosomes of a fruit fly show?
When the chromosomes of a fruit fly are stained with chemicals, they reveal straight, dark bands along their length. These bands match the locations of particular genes. The chromosomes of fruit flies gave scientists their first glimpse of genetic variations between species and individuals.
