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.

Instructional Ideas

• Read the paper from which the research originated to learn more about the methodology
• To shorten the amount of class time needed, have pupils watch the video at home before the lesson and finish the worksheets individually at home after collecting data in class

Classroom Considerations

• Relies on prior knowledge of genetics, genotype, phenotype, homozygous, heterozygous, dominant recessive, generations, test crosses, Punnett squares, ratios, and proportions

Pros

• Provides teacher tips for everything from the best print margins to the ideal groupings based on prior knowledge
• Includes an answer key for each question and possible answers to data collection

Cons

• None
