Dominant Fly Activity You and your partner(s) will get a baggie with two plastic eggs. The eggs represent the male and female gametes that have come together to create your baby fly…..aw!!! cute!  Fill in your chart listing what alleles your baby fly inherited, etc. Draw your fly at the bottom of your paper.
