Today, a few breeds are believed to be of Latin American origin, such as the Chihuahua dog and two hairless breeds. However, the evolutionary history of dogs in this region is still poorly understood. In this poster, we present the results of a palaeogenomic analysis tracking down the trajectory of the maternal dog lineages from ca. 5,000 years ago to the present. We observe a stepping-stone model of spread and we can link the arrival of dogs in South America with the emergence of agriculture. Later, we detect the replacement of pre-contact American dogs with Eurasian lineages and their persistence until present-day. One breed, the Chihuahua, stands aside as maintaining a pre-contact maternal signature that confirms the Mexican origin of the breed.
#31 The 99 lives Cat Genome Consortium: Updates and discoveries.

99 Lives Consortium, Department of Veterinary Medicine & Surgery, College of Veterinary Medicine, University of Missouri, Columbia, MO, USA The current 99 Lives Cat Genome Sequencing Consortium dataset is composed of 340 whole genome sequences (WGS) and has been aligned to the Felis catus V9.0 genome for variant detection using GATK best practices. Data is also available from 61 cat whole exome sequences. Approximately 28% of the data has been provided by the University of Missouri, 11 institutions have contributed between 10 to 35 sequences each, while 15 other groups have provided < 5 sequences each. The pet food industry has accounted for 12 genome contributions. Overall, > 60 participants from 53 institutions participate in the 99 Lives Consortium. The cat representation includes 99 cats from 33 recognized breeds, ranging from singletons for 14 breeds to Orientals / Siamese (n = 18), Burmese (n = 21), Maine Coon (n = 21), and Persians / Himalayans (n = 39). An additional 39 cats are mixed breed. Approximately 105 cats represent random bred populations, with a major as western European but cats from the Middle East, the Mediterranean and Asia have some representation. Several trios are available as well as a few larger familial groupings. New genome data from the
