Collie

Collie genetic profile from the CanVAS Atlas. 20 dogs in the Atlas, heterozygosity 0.24. Nearest relatives, trait loci frequencies, cohort distribution.

What the atlas says about Collie

In the atlas, the Collie clusters consistently as Collie (100% of the 20 dogs here). At the trait loci, HMGA2 runs lower than average (0% here vs 56%); RSPO2 runs lower than average (9% here vs 55%). Dogs here sit in a relatively sparse region of the atlas, fewer close neighbors than typical.

Ranks 12 of 107 on the bottleneck severity scale, well into the upper quartile of population contraction. High breed predictability score (2.85), individual dogs of this breed reliably cluster together genetically. Only 20 dogs of this breed in the atlas, modestly sampled.

Closest genetic neighbors in the atlas: Shetland Sheepdog, Pembroke Welsh Corgi, Cardigan Welsh Corgi, Australian Shepherd, and Border Collie.
