What the frequency means

KRT71 chr27:44.1Mb. Curl. CAVEAT: poorly tagged on the typed backbone - the curl-causing variant in Poodles is a single SNP not well captured at this rep SNP. Frequencies here may not predict curl phenotype reliably.

High frequency means

curly-coat allele common

Low frequency means

straight-coat allele common

Methodology

Frequency is measured at the typed-backbone 27:43395393 on chr27, 44.2 Mb (55 kb from the gene body). Alleles T/C. Coordinates from ensembl symbol UU Cfam GSD 1.0. Per-breed frequencies are computed across all CanVAS dogs labelled with that breed (missing genotypes excluded). See methodology for the full pipeline.
