A fish species you are lakes they are shorter and wider. You collect fish eggs from each location and rear the fish in an aquarium In your lab. Once they are adults, you measure their length & width and find that fish from rivers and streams have the same average length & width. Based on this study, what is the most reasonable conclusion you can make about body shape in this species? LAKE RIVER LAB Lake Directional selection has led to the evolution of body shape in one of the populations. Differences in body shape seen in the field are likely due to genetic drift.

Question
pome A fish species you are studying lives in both rivers and lakes. In rivers, they are skinny and long, whereas in lakes they are shorter and wider. You collect fish eggs from each location and rear the fish in an aquarium in your lab. Once they are adults, you measure their length & width and find that fish from rivers and streams have the same average length & width. Based on this study, what is the most reasonable conclusion you can make about body shape in this species? LAKE RIVER LAB Lake Lake River O Directional selection has led to the evolution of body shape in one of the populations. O Differences in body shape seen in the field are likely due to genetic drift. Differences in body shape seen in the field are due to phenotypic plasticity. O We can't make any of these conclusions based on this information alone.
