GENETIC REFERENCE & SCIENTIFIC NOTES
- Dominant Opal (Od): Homozygous Od/Od is semi-lethal. Offspring may hatch but often exhibit weak physical constitutions.
- Toy Stencil (Ts) Complex: Ts2 is treated as incomplete dominant; Ts3 and fs as recessive.
- Probability Variance: Total probability may not always sum to exactly 100% due to decimal rounding.
- Disclaimer: All results are mathematical probabilities based on standard models.
