Week at Clay HS
posted by: abeebe
I ended the school year with some great students over at Clay HS. Even though it was the second to the last week of the school year, these students were on task, and really showed lots of interest in the gloFISH. We had very good success in breeding the fish, and were able to study quite a few crosses of the different colored fish. We had green gloFISH x albino, red gloFISH x albino, and orange gloFISH x albino offspring. The results of the phenotypes of the offspring were somewhat confusing. Some students saw 2 or 3 different colored floFISH embryos/larvae at the end of the experiment. These fish were the product of a cross between one gloFISH and one albino. How were they observing red, green and orange offspring from a red gloFISH x albino?? I am not sure. It was encouraging that the fluorescing pigment appeared to be observable in the 6 day old larvae. We will need more crosses to see how the genetics is actually playing out with these gloFISH zebrafish.
Here are pictures of students at work.
I have put together a short video of the students at work too-it’s my first job editing a video, so please forgive the mistakes. I had difficulty being able to go back and edit…. I am learning! Hopefully my next video will be better.

The video looked great! I didn’t see any mistakes
It does seem strange that the red gloFISH x albino gave all the colors, you’ll have to let us know if you figure out what happened.
