Repeated sex chromosome evolution in vertebrates supported by expanded avian sex chromosomes

This dataset contains genome assemblies for the following species: Alauda arvensis, Alauda razae, Eremophila alpestris and Panurus biarmicus. The DNA used for these assemblies was extracted som a single adult male per species, and paired-end sequenced (150 base pairs) on an Illumina HiSeqX machine. The sequence data was assembled using Spades v3.5.0 using kmer lengths 21,33,55,77 and 127 and setting --careful. The assemblies contains scaffolds longer than 1000 base pairs. The data was generated for the study "Sex chromosome evolution in vertebrates supported by expanded avian sex chromosomes" by Hanna Sigeman, Suvi Ponnikas, Pallavi Chauhan, Elisa Dierickx, M. de L. Brooke and Bengt Hansson. More information can be found in the manuscript. The raw reads used for the genome assemblies can be found on the NCBI Sequence Read Archive under the Bioproject accession PRJNA578893.
