F1 and F2 Generations

Weeks Two Through Four

The flies that hatched from the initial vial are the F1 generation. Immobilize and carefully observe these flies. Note and record any genetic variations.

HINT: Be sure to separate males from females to see if there are variations related to sex.

Set up a new vial and transfer some of the F1 flies to it.

What generation will their offspring be?
