Genetics is often described as the hardest "easy" subject in biology. The concepts—DNA, alleles, dominance, recombination, mutation—are simple enough to memorize in an afternoon. Yet, when students open their textbooks and encounter a complex pedigree chart or a dihybrid cross with linked genes, panic sets in. Why the disconnect?

Clearly assign letter symbols to your alleles. Use uppercase for dominant alleles and lowercase for recessive alleles (e.g., Yet, when students open their textbooks and encounter
