Fruit Flies

This picture is from my genetics lab. Basically we analyzed the different pigments in mutant flies that have different eye colors. To accomplish this, we smashed fly heads onto chromatography paper. Then we set the bottom edge of the paper in chromatography solution. As the solvent soaked up through the paper, it separated the different pigments on the paper. The six streaks correspond to the six kinds of flies we analyzed. The streak that doesn't show any color is from the white-eyed flies.

White-Eyed Fly
Here is a female white-eyed mutant fly.

What do you call a fly with no wings? A walk. This is one of the other mutations we experimented with in our lab.

Sea Urchin Development

Fertilized Egg Two Cells Four Cells Eight Cells
Fertilization After 20 minutes 45 minutes 1.5 hours

In my Developmental Biology class we fertilized sea urchin eggs and watched them develop. In the first picture the black dots on the clear membrane are sperm.


This is a chemical called luminol that I made
in Organic Chemistry Lab. Neat, huh?
