Today – Fruit Fly Set-up:

Each group will set up 2 vials with breeding fruit flies; these flies will constitute our breeding population for our population genetics experiment.

Fruit Fly Genetics

We will only look at one trait: eye color

Wild type eyes (red, R) are dominant to sepia eyes (brown, r)

Our experiment begins with the F1 generation:

RR x rr = Rr

Our F1 flies (Rr) will all have red eyes

Setting up the vials

Each group will set up two vials, each with a minimum of 5 females and 5 males

Start by placing FlyNap wands in stock cultures; prepare new vials:          

–      Add equal amounts of media and water to bottom of each vial

–      Add a few granules of yeast to each vial

–      Prepare labels for vials

Sort adult flies into males and females

•       Add equal numbers of males and females to each vial (minimum 5 each); cap vials and place into incubator
