Answer the question you selected for profile question 2 here (300 words):
I had an aquarium with tropical fish when I was in grade school and I raised fish called swordtails. I decided to do an experiment on the inheritance of color between a red bodied, black-finned male swordtail and a solid green female. The babies all looked like their father, so I knew that red body and black fins were a dominant trait. Once the babies grew up and had babies themselves, there were four colorations: red body with black fins, green body with black fins, red body with red fins, and green body with green fins. It wasn't until I took a college course that I understood that the body color and fin color were likely controlled by different genes and inherited independently of each other.
