Genetics Fly experiment

Genetics


In this task we have been given virgin flies, some(prenominal) male and effeminate from 2 different types fundamental and ebony fruit flies. The genotypes for these flies argon:
(vg + vg+ ebeb)
(vgvg eb+ eb+)
Aim
Are task in this experiment is to do a series of genetic crosses to pay back whether these genes e.g the flies body colour and the flies wings, are joined on the same chromosome or on separate chromosomes.

Equipment
drop nap
Stock bottle of ebony flies
Stock bottle of rudimentary flies
Yeast
Water
Small 1 cm by 3 cm paper
Breading pipework
Foam lid

Method

First of all the flies are interpreted from their main colony container a few are released into certain pipette trays ebony in one sealed tray and vestigial in the other tray. Next you a chemical post name Fly nap to render the flies lost once the effect has effected all flies we prat consequently study each fly and find the sexual activity of each. We thus decided that the we would take 3 ebony female and 3 male vestigial. And put them in a breading tube with a yeast mixture at the bottom for nutriment and paper to land on and a foam pourboire for oxygen. Once the files matted we took the parents out and waited 2 weeks for them to hack and collapse we have decided to make an F1 and F2 generation. This would be are head start F1 generation.



Then to make are F2 generation we would take 3 male and 3 female from are F1 generation and then the same process is repeated with a breading tube and we then have are F2 generation and the parents are released. Before the publication are mature and start to become a flies.





hither below is a list of are fly types and are total number of flies for are three sets of F1 generation.
