Mouse Breeding & Mendelian Ratio Predictor
How to Use:
1. Genetic Cross: Select the genotypes of Parent 1 and Parent 2. You can calculate a single gene cross or a two-gene cross (e.g., Flox and Cre).
2. Colony Planning: Enter the desired number of pups for a specific genotype to estimate the total number of litters and pups required.

Breeding Estimation
To obtain 0 pups with a 0% probability, you need:
• Expected Total Pups (All Genotypes): 0
• Expected Number of Litters: 0
💡 Breeding Tip: A standard breeding pair produces roughly 1 litter every 4-5 weeks. If you need 4 litters quickly, you should set up 3-4 separate breeding cages simultaneously rather than waiting for one pair to produce multiple litters.
