How to Use
Each parent is two adjacent loci (for example AaBb). The four-by-four cross enumerates genotype probabilities only; no dominance or phenotype interpretation is applied.
Use measured values and a documented convention. This calculator does not provide medical, veterinary, phenotype, or laboratory-method advice.
FAQs
What assumptions are used?
Enumerate two-locus offspring genotype probabilities from explicit parent genotypes. Every mass, volume, sequence adjustment, genotype, and locus convention is visible or entered explicitly.
