New Cultures

We cleaned out our old adult cultures completely today and replaced them with new adults taken from other cultures.

In the crossing tubes, a single fly remained alive in each.

Crosses Update

Two of the genetic crosses, vestigal with white eyed and vestigal with wild type have completely died out. Also, our adult white eyed and vestigal populations are depleted as well. We are now creating new adult populations from the class room cultures, and hopefully these will produce enough virgins needed for successful genetic crosses and use of these crosses to evaluate Medelian principles of genetics in the fruit flies.

Crossing Flies Day One

After collecting a small amount of virgin females, we arranged the following test cultures to cross different phenotypes:

• 2 Vestigal Virgins with two White Eyed Males
• 2 Wild Type Virgins with two White Eyed Males
• 2 Wild Type Virgins with two Vestigal Males

We will watch the reproduction of these cultures, along with other cultures, to see how inheritance patterns change with differences in the parent pairings.
Further research will be added in a later post to describe the expected phenotypes of the new offspring.
