I made a quick trip to the lab this morning (it’s -25°C! I walked quickly!) to take some fly photos for this week’s genetics lab. The students are doing a simple complementation assay with fly eye colors — can you tell which one is scarlet (st) and which one is brown (bw)? Every year it’s a struggle to get them to recognize even obvious mutations like these, but it’s not the students’ fault. This is their first time working with flies, and it’s easy to get overwhelmed with the alienness of Drosophila.
Me, I’m always impressed with how beautiful their eyelashes are.
Of course, immediately after their glamorous photo shoot, these flies were sacrificed on the altar of the spider gods.
