Total 16 combinations

  • Law of independent assortment: two gene loci segregate independently, so a double heterozygote (AaBb) makes 4 gametes — AB, Ab, aB, ab.
  • Classic check: AaBb × AaBb gives the 9:3:3:1 phenotypic ratio; AaBb × aabb (test cross) gives 1:1:1:1.
  • 9:3:3:1 deviation suggests gene linkage; a 9:7 or 15:1 ratio indicates epistasis.
  • Box colors: darker = both dominant, lighter = one or none — use them to see phenotype groups at a glance.
