Genotypes & major-gene panel
SNP genotypes from your lab. Illumina FinalReport (AB calls) and VCF are read today; other formats are added when a lab supplies a sample file, and herd-sized files are loaded for you. Genemap blends genomic and pedigree relationships and solves breeding values for genotyped and ungenotyped animals on the traits that have published cattle parameters: four growth traits together, others one at a time. The major-gene panel below also reads each animal's genotype calls for myostatin, polled, recessive-defect carriers, and performance markers.
1Genotype intake
There is one place to bring animals in — the Upload Herd tab. It accepts BREEDPLAN / Zoetis Inherit Select / IGS / Igenity EBV & genomic exports and saves your herd so it powers Live Rank, Herd Profit and this page.
2Genomic relationships
Build the genomic similarity layer across the genotyped subset of your herd. Computed in-browser for ≤ 500 animals × 50K SNPs; larger herds are sent to the server, which currently evaluates up to about 1,190 animals in the pedigree.
3Multi-trait genomic solve
Solve breeding values across the trait set. Traits are solved one at a time and linked through published genetic correlations over repeated passes; it is not one joint solve. Published correlations exist for the four growth traits only.
3aMaternal evaluation (MILK)
Splits a calf's 200-day or birth weight into the part that is the calf's own genetics and the part its dam provided. The dam's part, for 200-day weight, is reported as MILK. Available for Brahman and Brahman-derived composite herds, on published variance components. Every recorded calf needs its dam identified; a calf with no dam is left out and counted. Results are shown here and are not written to your animals.
3bCarcase & MSA → GEBV
Carcase records (from Carcase import) go into the Genemap evaluation above (stage 3): it reads them with their contemporaries, relatives and genotypes, and Apply records the resulting EBVs against that run, labelled as Genemap EBVs. A published BREEDPLAN / TACE / IGS / LAMBPLAN evaluation is never changed — it stays in the association history beside the Genemap figures. MSA Index is an eating-quality composite, not a heritable trait, so it is deliberately not used as a breeding-value phenotype.

4Major-gene dictionary
Per-locus DNA marker effects we apply as fixed effects in the evaluation. When a SNP call is present on the animal, the platform reads the genotype, computes carrier status, and incorporates the effect into the breeding value. The herd risk panel below scans every recorded sire × dam pairing in your herd for at-risk recessive-lethal matings.
| Locus | Category | Target trait | Per-allele effect | Dominance | Breed-frequency hint | Herd carriers |

Herd carrier × carrier risk scan
Cross-checks every recorded sire × dam pairing in your herd against the recessive-lethal and recessive-defect loci above. Anything that lights up here is a 25% risk of producing affected progeny — don't repeat the mating.
