Genetics | Dihybrid Cross (Example 2)

The video tutorial explains the process of performing a dihybrid cross, focusing on genes A and B, which code for height and speed, respectively. Both maternal and paternal genotypes are heterozygous for these genes. The tutorial covers setting up the dihybrid cross, filling in the 16 cells, and calculating both genotypic and phenotypic ratios. It emphasizes the importance of correctly setting up the cross and provides a shortcut for memorizing the phenotypic ratio of 9:3:3:1 when crossing two heterozygotes.
