Feline 63K SNP chip data originated from the domestic cat in Japan

Pedigreed cats have traditionally been mated with close relatives, which increases the risks for inbreeding depression and genetic disorders. We evaluated the genome-wide population structure and the degree of inbreeding of 1022 cats, including 13 pedigreed and two random bred populations from Japan and the USA, using single nucleotide polymorphism array-based data. Methods Thirteen pedigreed and a random-bred populations from Japan were genotyped by using Infinium Feline 63k Iselect Dna Array (Illumina Inc.) to compare the USA population.
