Genetic similarity between poodle subgroups and eight other dog breeds. Neighbor-joining analysis of allelic composition at 27 microsatellite loci. Calculations are based on Nei's  standard genetic distances (DS), and numbers on branches correspond to bootstrap values from 1000 bootstrap resamplings across loci (only values above 50 are shown). Poodle 2, black and brown medium sized poodles; Poodle 3, black and brown miniature and toy poodles; Poodle 4, silver and white medium sized, miniature and toy poodles; Poodle 5, apricot medium sized, miniature and toy poodles.
