The ability to identify genetic markers in nonmodel systems has allowed geneticists to
construct linkage maps for a diversity of species, and the sex-determining locus is often …

The eukaryotic genome is packaged into transcriptionally active euchromatin and silent
heterochromatin, with most studies focused on the former encompassing the majority of …

Although transitions of sex-determination mechanisms are frequent in species with
homomorphic sex chromosomes,,, heteromorphic sex chromosomes are thought to …

While short-read sequencing technology has resulted in a sharp increase in the number of
species with genome assemblies, these assemblies are typically highly fragmented …

Sex chromosomes have many unusual features relative to autosomes. Y (or W)
chromosomes lack genetic recombination, are male-(female-) limited, and show an …

Simple satellites are tandemly repeating short DNA motifs that can span megabases in
eukaryotic genomes. Because they can cause genomic instability through nonallelic …

Sex-chromosomes have formed repeatedly across Diptera from ordinary autosomes, and X-
chromosomes mostly conserve their ancestral genes. Y-chromosomes are characterized by …

Background Satellite DNA can make up a substantial fraction of eukaryotic genomes and
has roles in genome structure and chromosome segregation. The rapid evolution of satellite …

Sex chromosomes can differ between species as a result of evolutionary turnover, a process
that can be driven by evolution of the sex determination pathway. Canonical models of sex …

DNA in situ hybridization (DNA ISH) is a commonly used method for mapping sequences to
specific chromosome regions. This approach is particularly effective at mapping highly …
