Dark, curly, non-red, and thick hair are all dominant genes. The video begins by defining phenotype, genes, alleles, and genotype. Scholars learn how alleles determine genotype, which directs phenotype, using red hair as the example. The narrator uses the Hardy-Weinberg equation to work problems with viewers.
