Archetype Sub-90 Dry-Wipe Invariant (Non-Mendelian Ratios (2:1 Lethal Alleles, Codominance, Dihybrid & Multi-Cross Phenotypic Ratio Tables)): Spot non-standard ratios immediately: 2:1 live offspring ratio = homozygous lethal allele (1/4 die in utero); 1:2:1 phenotypic ratio = codominance/incomplete dominance (e.g. I^A I^B or coat colour); in multi-cross tables, identify the homozygous recessive test-cross row first.
