SummaryA hands-on activity in which students analyze the results of genetic crosses between stickleback fish with different traits.
A hands-on activity in which students apply the principles of Mendelian genetics to analyze the results of genetic crosses between stickleback fish with different traits. Students use photos of actual research specimens (the F1 and F2 cards) to obtain their data; they will then analyze the data they collected along with additional data from the scientific literature. In the extension activity, students use chi-square analysis to determine the significance of genetic data.
Appropriate for: high school biology (all levels)
