Instructional Ideas

• Pause video after first and second dihybrid crosses for teachers and scholars to process, ask questions, and discuss the results

Classroom Considerations

• To use the resource, you must have a computer, access to the Internet, and a projection system
• Video assumes scholars understand the following vocabulary: homozygous, heterozygous, genotypes, alleles, dominant, and recessive
• The fifth in a series of 31

Pros

• Includes a link to a slideshow that follows the video
• Contains the link to his video on genetic recombination and gene mapping

Cons

• None
