The complete sequence and comparative analysis of ape sex chromosomes. [PDF]
NatureApes possess two sex chromosomes—the male-specific Y chromosome and the X chromosome, which is present in both males and females. The Y chromosome is crucial for male reproduction, with deletions being linked to infertility1.

Gene-rich UV sex chromosomes harbor conserved regulators of sexual development
Science Advances, 2021 Moss sex chromosomes retain thousands of broadly expressed genes despite millions of years of suppressed recombination. Nonrecombining sex chromosomes, like the mammalian Y, often lose genes and accumulate transposable elements, a process termed ...

Sex-biased expression of sex-linked transcripts in spiny frogs with homomorphic sex chromosomes [PDF]
BMC GenomicsBackground The accumulation of sexually antagonistic mutations on chromosomes has been favored in driving the evolution of sex chromosomes. However, empirical evidence has been limited to species with heteromorphic sex chromosomes, where the patterns of ...

Chromosome complement and meiosis in three species of the Neotropical bug genus Antiteuchus (Heteroptera, Pentatomidae, Discocephalinae) [PDF]
Genetics and Molecular Biology, 2006 Orcein staining of spermatocytes was used to study the meiotic behavior of holocentric chromosomes in three member of the genus Antiteuchus (commonly known as stink bugs). We describe and illustrate the karyotype of Antiteuchus mixtus, A. sepulcralis and

Using conventionalF-statistics to study unconventional sex-chromosome differentiation [PDF]
, 2017 Species with undifferentiated sex chromosomes emerge as key organisms to understand the astonishing diversity of sex-determination systems. Whereas new genomic methods are widening opportunities to study these systems, the difficulty to separately ...

Unusual Diversity of Sex Chromosomes in African Cichlid Fishes [PDF]
Genes, 2018 African cichlids display a remarkable assortment of jaw morphologies, pigmentation patterns, and mating behaviors. In addition to this previously documented diversity, recent studies have documented a rich diversity of sex chromosomes within these fishes.

Numerous transitions of sex chromosomes in Diptera.
PLoS Biology, 2015 Many species groups, including mammals and many insects, determine sex using heteromorphic sex chromosomes. Diptera flies, which include the model Drosophila melanogaster, generally have XY sex chromosomes and a conserved karyotype consisting of six ...

Allopolyploidization from two dioecious ancestors leads to recurrent evolution of sex chromosomes [PDF]
Nature CommunicationsPolyploidization presents an unusual challenge for species with sex chromosomes, as it can lead to complex combinations of sex chromosomes that disrupt reproductive development.

Convergent evolution of chicken Z and human X chromosomes by expansion and gene acquisition [PDF]
Nature, 2010 In birds, as in mammals, one pair of chromosomes differs between the sexes. In birds, males are ZZ and females ZW. In mammals, males are XY and females XX.
