Predict the Possible Phenotypes of Offspring Using Punnet Squares
This biology lesson focuses on explaining phenotype inheritance using Punnett squares. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students read a genetic cross, identifying the dominant and recessive traits, and determine the genotype of each parent. Then, they label the Punnett square with the alleles of each parent. Next, students combine the alleles of each parent to determine the genotype of each offspring. Finally, they identify the phenotype and answer the questions. In addition to the lesson, there is one page of Independent Practice and review modeled after current adaptive testing items.
