The Red Fox Y-Chromosome in Comparative Context

While the number of mammalian genome assemblies has proliferated, Y-chromosome

such as its high repeat content, that present challenges to assembly with short-read, next-generation

dog (Canis lupus familiaris), and grey wolf (Canis lupus lupus), providing the opportunity to examine

data-driven approach to identifying Y-chromosome sequence among the scaffolds that comprise the

of cats, dogs, and wolves were identified. Next, analysis of the resequenced genomes of 15 male

copy number variation consistent with the heterogametic chromosome. Analyzing variation across

The gene content of these scaffolds is consistent overall with that of the Y-chromosome in other

has been reported in related species and fewer copies of SRY than in other canids. The assignment of

genome while providing resources for future analyses of canid Y-chromosome evolution.
