What is X. couchianus and X. hellerii genome models provide genomic variation insight among Xiphophorus species about?

## Background: Xiphophorus fishes are represented by 26 live-bearing species of tropical fish that express many attributes (e.g., viviparity, genetic and phenotypic variation, ecological adaptation, varied sexual developmental mechanisms, ability to produce fertile interspecies hybrids) that have made attractive research models for over 85 years. use of various interspecies hybrids to investigate the genetics underlying spontaneous and induced tumorigenesis has resulted in the development and maintenance of pedigreed xiphophorus lines specifically bred for research. the recent availability of the x. maculatus reference genome assembly now provides unprecedented opportunities for novel and exciting comparative research studies among xiphophorus species. ## Results: We present sequencing, assembly and annotation of two new genomes representing xiphophorus couchianus and xiphophorus hellerii. the final x. couchianus and x. hellerii assemblies have total sizes of 708 mb and 734 mb and correspond to 98 % and 102 % of the x. maculatus jp 163 a genome size, respectively. the rates of single nucleotide change range from 1 per 52 bp to 1 per 69 bp among the three genomes and the impact of p
