Beginner's Guide to Punnett Squares

This Beginner's Guide to Punnett Squares video also includes:

Show learners how to apply genotypes of parents to a Punnett square to determine potential genotypes and phenotypes of offspring with a video that explores monohybrid crosses and then complete a dihybrid cross as well.

Instructional Ideas

  • Show this second video before the first one in this series
  • Pause video to allow learners to complete the crosses shown and to discuss answers
Classroom Considerations

  • Assumes learners understand alleles
  • Video two in a series of 31 
Pros

  • the explanation of simple monohybrid crosses showing complete, incomplete, and co-dominance is easy for pupils to follow
  • Completes a sex-linked cross in a simple monohybrid cross; great for your class to see and understand sex-linkage
  • Young scientists walk through two dihybrid crosses to see genotype and phenotype results; these activities seem complex but the crosses shown are very effective
Cons

  • None
