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
