This Using Genetic Crosses to Analyze a Stickleback Trait activity also includes:
Two fish appear different, but how do scientists determine their genotypes? Scholars practice performing test crosses to determine the genotypes of fish given their phenotypes. They answer in-depth comprehension questions and complete statistical analyses of the data they collect using the provided cards.
- Read the paper from which the research originated to learn more about the methodology
