Genome-wide study suggests inheritance of personality traits in Toy Poodles and Miniature Dachshunds
Domestic dogs exhibit significant diversity in both morphology and personality. Recent studies focusing on large-breed dogs reported the contribution of genetic factors to personality. However, the genetic influence in small-breed dogs remains unexplored. In the present study, we investigated the personality of two small-breed dogs using a questionnaire and genome-wide single-nucleotide polymorphism data obtained from 301 Toy Poodles and 183 Miniature Dachshunds using the Illumina CanineHD 230K SNP BeadChip. The factor analysis conducted on a questionnaire consisting of 39 items identified seven factors. Among the seven personality factors, ‘activeness’ in Toy Poodles and ‘human-directed sociability’ in Miniature Dachshunds had an estimated heritability of 0.425 (SE = 0.311) and 0.514 (SE = 0.355), respectively. In addition, genome-wide association study suggested that two genomic regions possibly affect personality. The dog breeds focused on in this study are most popular in Japan, thus their information is in high demand.
期刊介绍：
Animal Genetics reports frontline research on immunogenetics, molecular genetics and functional genomics of economically important and domesticated animals. Publications include the study of variability at gene and protein levels, mapping of genes, traits and QTLs, associations between genes and traits, genetic diversity, and characterization of gene or protein expression and control related to phenotypic or genetic variation.
The journal publishes full-length articles, short communications and brief notes, as well as commissioned and submitted mini-reviews on issues of interest to Animal Genetics readers.
